Procedure

2-(1-((2-(2-aminophenylamino)-4-morpholinopyrido[3,2-d]pyrimidin-6-yl)methyl)piperidin-4-yl)propan-2-ol was reacted with 2,2-difluoropropanoic acid (2 eq), O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (HATU, 1.5 eq) and DIPEA (4 eq) in DMF (4 mL) for 1 hr (hour). The reaction mixture was extracted with EtOAc and bicarbonate solution and the organic layer was dried with Magnesium sulfate, filtered, evaporated and purified via flash column chromatography to get 50 mg of 2,2-difluoro-N-(2-(6-((4-(2-hydroxypropan-2-yl)piperidin-1-yl)methyl)-4-morpholinopyrido[3,2-d]pyrimidin-2-ylamino)phenyl)propanamide. This intermediate was reacted with acetic acid (1.6 mL) over one week to yield 4.1 mg of 120 following reverse phase HPLC purification. MS (Q1) 552.3 (M)+
