Procedure
A solution of 8-methyl-2-methanesulfonyl-8H-pyrido[2,3-d]pyrimidin-7-one (200 mg, 0.83 mmol) in 2 mL of n-butylamine was stirred at room temperature for 10 minutes. The reaction mixture was partitioned between ethyl acetate and water, and the organic layer was washed with saturated sodium bicarbonate and brine, dried over magnesium sulfate, and concentrated in vacuo. A 4:1 mixture of hexane:ethyl acetate was added to the residue and the resultant solid collected by filtration to give 154 mg (79%) of 2-butylamino-8-methyl-8H-pyrido[2,3-d]pyrimidin-7-one, mp 146-147° C.
