Procedure: LAH (0.571 g, 15.05 mmol) was added to a 3-neck dry flask and THF (50 mL) was added on cooling. A solution of 4-morpholin-4-ylmethyl)-benzoic acid ethyl ester (3.0 g, 12.04 mmol) in THF (10 mL) was added slowly on cooling. After completion of addition, the reaction mixture was heated at reflux for 3 h. The reaction mixture was cooled to 0° C. and a 10% NaOH solution was added carefully followed by water. The organic layer was separated and the aqueous layer was extracted with ethyl acetate. The combined organic layers were washed with water, brine and dried over Na2SO4. The solvent was removed to give (4-morpholin-4-ylmethyl phenyl)methanol (2.0 g, 80%). To the 3-flask anhydrous CH2Cl2 (100 mL) was added and cooled to −78° C. Oxalyl chloride (1.47 g, 11.59 mmol) and DMSO (1.5 g, 19.32 mmol) were added at −78° C. The reaction mixture was stirred for 15 min at −78° C. A solution of (4-morpholin-4-ylmethyl phenyl)methanol (2.0 g, 9.66 mmol) in CH2Cl2 (10 mL) was added at −78° C. and the mixture was stirred at −78° C. for 1 h. Then, Et3N (3.9 g, 38.64 mmol) was added. The reaction mixture was allowed to come at room temperature. Water was added and the organic layer was isolated. The aqueous layer was extracted with CH2Cl2. The combined organic layers were washed with water, brine and dried over Na2SO4. Then solvent was removed to give crude 4-morpholin-4-ylmethyl benzaldehyde (1.6 g, 81%). the mixture was stirred at −78° C. for 1 h to come at room temperature the organic layer was isolated The aqueous layer was extracted with CH2Cl2 The combined organic layers were washed with water, brine dried over Na2SO4 Then solvent was removed

Procedure: {2-Chloro-4-[3-(4-chloro-phenylethynyl)-5-hydroxy-phenylsulfanyl]-phenoxy}-acetic acid ethyl ester (274 mg; 0.58 mmol) was dissolved in THF (15 mL) in a dried reaction flask under an atmosphere of nitrogen. (4-Morpholin-4-ylmethyl-phenyl)-methanol (100 mg; 0.48 mmol) and tributylphosphine (0.21 mL; 0.87 mmol) was added followed by 1,1′-(Azodicarbonyl)dipiperidine (0.22 g; 0.87 mmol) dissolved in THF (10 mL). The reaction mixture was stirred at room temperature for 5 h, filtered and evaporated in vacuo. The crude product was purified by prep. HPLC (method A). Yield: 250 mg. HPLC-MS: m/z: 663.0 (M+H); Rt: 2.47 min. filtered evaporated in vacuo The crude product was purified by prep

Procedure: To a suspension of NaH (99 mg, 2.27 mmol) in ACN (4 mL) was added a solution of N-(4-hydroxymethylbenzyl)morpholine 313 mg, 1.51 mmol) in ACN (4 mL). The mixture was stirred 1 h at rt. Then (2-chloropyrimidin-4-yl)(4-ethyl-1,3-thiazol-2(3H)-ylidene)acetonitrile (200 mg, 0.76 mmol) was added portion wise. The resulting mixture was heated up at 80° C. for 5 h. After cooling down to rt the ACN was evaporated. EtOAc (5 mL) was added to the residue. After one night at 4° C., the yellow solid was filtered off affording the title compound as a free base (HPLC (max plot) 73.9%). The solid was taken up in DCM and excess TFA then ether were added. The precipitate formed was filtered off, washed with ether (3×) then dried under reduced pressure at 40° C. overnight, affording 409 mg of the title compound as a diTFA salt (Yellow powder, Y=81.1%) The resulting mixture was heated up at 80° C. for 5 h was evaporated EtOAc (5 mL) was added to the residue After one night at 4° C. the yellow solid was filtered off
