Reaction Steps

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.
