Reaction Steps

To a solution of (Z)-1-cyclopropyl-4-(dimethylamino)-3-(2-(pyridin-4-ylamino)pyrimidin-4-yl)but-3-en-2-one (9) (50 mg, 0.155 mmol) in DMF (541 μl), (S)-1-(1-hydroxypropan-2-yl)guanidine (147 mg, 0.773 mmol) and potassium carbonate (214 mg, 1.546 mmol) were added, and the reaction mixture was stirred at 90° C. for 3 hours. The crude product was purified by reverse-phase HPLC [30-90% organic phase over 15 minutes] followed by Biotage™ silica gel chromatography [10 g SNAP column, 100% DCM to 12% MeOH/DCM] to obtain the desired product (23.9 mg, 41%).
