Procedure

To a solution of N-(2-aminophenyl)acrylamide (TFA salt) (10 g, 38.6 mmol) in N-methyl pyrrolidinone (30 mL) was added DIPEA (12.6 g, 98.36 mmol), and 2,4,5-trichloropyrimidine (9.5 g, 49.18 mmol), and the mixture was stirred at rt for 16 h. TLC showed completion of starting material (TLC system: 50% ethyl acetate/hexane, (Rf): 0.5). The reaction mixture was diluted with ethyl acetate (100 mL) and washed with water (3×50 mL). The organic layer was separated, dried over sodium sulfate and concentrated to obtain the crude compound (11 g). MS m/z: 309.1 (ES+, M+1).
