Procedure

To a reaction solution of 5-bromo-2-(2,5-dimethyl-1H-pyrrol-1-yl)-6-methyl-N-(pyrrolidin-1-yl)pyrimidin-4-amine (3.14 g, 8.97 mmol) in anhydrous methylene chloride (120 ml) and hunig's base (4.68 ml) was added slowly a solution of acryloyl chloride (0.80 ml, 9.86 mmol) in methylene chloride (30 ml) dropwise at R.T. After stirring at R.T for 60 mins, the reaction mixture was concentrated under reduced pressure and the residue was purified by 120 g column eluted with 40% ethyl acetate:hexane to give the titled product weighted 3.5 g a white solid 97%
