Procedure

2-Chloro-4-morpholinopyrido[3,2-d]pyrimidine-6-carboxylic acid (0.12 g) was reacted with 2-(piperidin-4-yl)propan-2-ol (1.2 eq), HATU O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (1.2 eq) and DIPEA (3 eq) in DMF (3.2 mL) for 1 hour. The reaction was then extracted with EtOAc and bicarbonate solution and the organic layer was dried with Magnesium sulfate, filtered and concentrated to give (2-chloro-4-morpholinopyrido[3,2-d]pyrimidin-6-yl)(4-(2-hydroxypropan-2-yl)piperidin-1-yl)methanone in quantitative yield.
