Procedure: To a solution of 0.54 g (2 mmoles) of 5-bromo-4-(2,2-dimethyl-propylamino)-pyrimidine-2-carbonitrile and 0.75 g (4.3 mmoles) of 4-propargylthiomorpholine-1,1-dioxide in 5 ml of DMF are added 0.841 ml (6 mmoles) of triethylamine, 0.38 g (2 mmoles) of copper(I) iodide and 0.14 g (0.2 mmoles) of Pd(PPh3)2Cl2under nitrogen atmosphere. The mixture is stirred for 31 hours at 80° C. The mixture is filtered through celite, diluted with AcOEt, washed with H2O and brine, dried over Na2SO4 and concentrated under reduced pressure. The residue is purified by HPLC(H2O—0.1% TFA/CH3CN—0.1% TFA). Fractions are collected, basified with 5% aqueous NaHCO3, extracted with AcOEt, washed with brine, dried over Na2SO4 and concentrated under reduced pressure. The resulting residue is then purified by HPLC (n-Hexane/AcOEt) to give 0.01 g of desired 7-(2,2-dimethyl-propyl)-6-(1,1-dioxo-1λ6-thiomorpholin-4-ylmethyl)-7H-pyrrolo[2,3-d]pyrimidine-2-carbonitrile in 1.4% yield. The mixture is filtered through celite diluted with AcOEt washed with H2O and brine dried over Na2SO4 concentrated under reduced pressure The residue is purified by HPLC(H2O—0.1% TFA/CH3CN—0.1% TFA) Fractions are collected extracted with AcOEt washed with brine dried over Na2SO4 concentrated under reduced pressure The resulting residue is then purified by HPLC (n-Hexane/AcOEt)

Procedure: To a solution of N-(4-chlorobenzyl)-8-iodo-1-methyl-6-(4-morpholinylmethyl)-4-oxo-1,4-dihydro-3-quinolinecarboxamide (300 mg), PdCl2(PPh3)2 (19.1 mg), and CuI (5.2 mg) in Et2NH (6.2 mL) is added 4-propargylthiomorpholine-1,1-dioxide (103.8 mg). Anhydrous DMF (18 mL) is added to help solubilize the reactants (also requires sonication). The reaction is stirred at room temperature overnight, then condensed. The resulting residue is placed under high vac to remove residual DMF. The crude product is dissolved in CH2Cl2 and partitioned between CH2Cl2 and H2O. The aqueous layer is extracted with CH2Cl2 (2×). The combined organic layers are dried over Na2SO4, filtered, and condensed. The crude product is adsorbed onto silica and chromatographed (eluent 100% CH2Cl2 (1L), 0.5% MeOH in CH2Cl2 (1L), 1% MeOH in CH2Cl2 (1L), 1.5% MeOH in CH2Cl2 (1L), and 2% MeOH in CH2Cl2 (4L), and 2.5% MeOH in CH2Cl2 (3L)). Product-containing fractions are combined, concentrated, and further purified by HPLC.
