To a solution of (E)-N-(3-(3-(dimethylamino)acryloyl)phenyl)acetamide (46 mg, 0.2 mmol) in HOAc (5 mL) was added 5-amino-3-(4-phenoxyphenyl)-1H-pyrazole-4-carbonitrile (55 mg, 0.2 mmol). The mixture was stirred at 118° C. for 4 hr. Then the reaction mixture was concentrated to a residue and partitioned between ethyl acetate (100 mL) and brine (100 mL). Organic layer was separated, washed with brine (2×100 mL), dried over sodium sulfate and concentrated to afford 80 mg (90%) of N-(3-(3-cyano-2-(4-phenoxyphenyl)pyrazolo[1,5-a]pyrimidin-7-yl)phenyl)acetamide as a colorless oil. MS (ESI) m/e [M+1]+ 446.
