Reaction Steps

To a microwave vial was added 2-(2,5-dimethyl-1H-pyrrol-1-yl)-4-methyl-8-(pyrrolidin-1-yl)pyrido[2,3,d]pyrimidin-7(8H)-one (530 mg, 1.64 mmol) hydroxamine hydrochloride (1.14 g, 16.4 mmol) ethanol (20 ml) and water (2.92 ml). The vial was capped and refluxed at 100° C. After 3 h, the reaction mixture was concentrated to dryness under reduced pressure and the resulting residue was purified by column chromatography eluted with 10% 7N NH3 in MeOH:CHCl3 to give the desired product weighted 296 mg 74%
