Reaction Steps

Combine (R)-2-(2-(1-(7-oxo-5-trifluoromethyl-5,6,7,8-tetrahydropyrido[2,3-d]pyrimidin-4-yl)piperidin-4-yl)-4-(2,2,2-trifluoroethyl)-1H-imidazol-1-yl)ethyl methanesulfonate (1.04 g, 1.82 mmol), dimethylformamide (9.3 mL), and azetidine (1.11 mL, 9.0 eq) under nitrogen. Heat the reaction mixture at 50° C. overnight, then allow to cool to room temperature. Dilute with ethyl acetate. Wash the organic layer with water. Dry the organics over anhydrous sodium sulfate, filter, and concentrate in vacuo. Purify by normal phase chromatography, eluting with 10% methanol/dichloromethane to 10% 2 M ammonia in methanol/dichloromethane, to give the title compound, (R)-4-(4-(1-(2-(azetidin-1-yl)ethyl)-4-(2,2,2-trifluoroethyl)-1H-imidazol-2-yl)piperidin-1-yl)-5-(trifluoromethyl)-5,6-dihydropyrido[2,3-d]pyrimidin-7(8H)-one, as a white solid (0.49 g, 51%). MS (ES) m/z=532 [M]+.
