Procedure: To a stirred suspension of LAH (6.1 mmol) in THF (25 mL) is added dropwise a solution of 2-amino-1-morpholin-4-yl-2-phenylethanone (670 mmol) in THF (5 mL) at 0° C. The reaction mixture is refluxed for 2 hr, and then the reaction is quenched by the addition of Na2SO4-10H2O at 0° C. After stirring at room temperature for 0.5 h, the resulting mixture is filtered through celite, and the filtrate is concentrated in vacuo to give the title compound, which is directly used for the next reaction without further purification. The reaction mixture is refluxed for 2 hr the reaction is quenched by the addition of Na2SO4-10H2O at 0° C the resulting mixture is filtered through celite the filtrate is concentrated in vacuo

Procedure: To a solution of 2-cyano-4-(cyclohexylmethylamino)-pyrimidine-5-carboxylic acid (0.33 mmol, step 1.4) in DMF (2.0 mL) are added 2-morpholin-4-yl-1-phenylethylamine (69 mg, step 1.3), EDCl—H2O (0.50 mmol) and HOAt (0.50 mmol) at room temperature. After stirring at room temperature for 24 h, the reaction mixture is diluted with AcOEt. The mixture is washed with water, dried over Na2SO4, filtered, and concentrated in vacuo. The resulting residue is purified by RP-HPLC to give the title compound; 1H NMR (DMSO) δ 0.6-1.08 (m, 2H), 1.20-1.35 (m, 3H), 1.65-1.78 (m, 6H), 2.48-2.53 (m, 2H), 2.60-2.62 (m, 2H), 2.87-2.93 (m, 2H), 3.31-3.35 (m, 1H), 3.36-3.44 (M, 1H), 3.60-3.68 (m, 4H), 5.29-5.35 (m, 1H), 7.34-7.36 (m, 1H), 7.43-7.47 (m, 2H), 7.50-7.52 (m, 2H), 8.86 (s, 1H), 9.00-9.04 (m, 1H), 9.21 (d, 1H).

Procedure: 2-morpholino-1-phenylethanamine represented by Formula 113 (38.4 mg, 0.186 mmol) was slowly added to 4-benzyloxy-3,5-dimethylbenzoic acid represented by Formula 144 (52.5 mg, 0.205 mmol, purchased from Medizin Co. Ltd.) and diisopropylethylamine (0.13 mL, 0.745 mmol) in DMF (3 mL) solution at room temperature. After cooling the reaction mixture to 0° C. and adding 2-(1H-7-azabenzotriazol-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate methanaminium (HATU, 77.9 mg, 0.205 mmol) thereto, the mixture was agitated at room temperature for 24 hours. The reaction solvent was removed under reduced pressure and chloroform (2 mL) was added to the remaining concentrate to prepare a solution. The solution was washed with a potassium carbonate (K2CO3) solution, followed by separation to form an organic layer. After drying the organic layer with sodium sulfate (Na2SO4), the solvent was removed again under reduced pressure. The obtained vacuum-concentrated mixture was moved to a cartridge tube (6 mL, benzenesulfonic acid, 904030-WJ, UCT) using a small amount of ethyl acetate. Impurities were eliminated using methanol (15 mL) then separation and purification were conducted (using ethyl acetate/methanol/triethylamine, 20:2:1, v/v/v) to produce a benzamide compound represented by Formula 74 as a desired product (VVZ-080; 31 mg, 37% yield). The reaction solvent was removed under reduced pressure and chloroform (2 mL) was added to the remaining concentrate to prepare a solution The solution was washed with a potassium carbonate (K2CO3) solution followed by separation to form an organic layer After drying the organic layer with sodium sulfate (Na2SO4) the solvent was removed again under reduced pressure The obtained vacuum-concentrated mixture was moved to a cartridge tube separation and purification
