Procedure

To a solution of 2,4-dichloro-N-methylpyrimidine-5-carboxamide (400 mg, 1.95 mmol) in NMP (1 ml), N-(2-aminophenyl)acrylamide (316 mg, 1.951 mmol) and DIPEA (503 mg, 3.902 mmol) were added and heated at 120° C. for 1 h. TLC showed completion of starting material (TLC system: 5% methanol in DCM (Rf): 0.3). The reaction mixture was diluted with water (30 ml) and extracted with ethyl acetate (3×15 ml). The organic layer was separated, dried over sodium sulphate, and concentrated. Crude compound was purified by column chromatography using silica gel (100-200 mesh) with 2% methanol in DCM to obtain 4-(2-acrylamidophenylamino)-2-chloro-N-methylpyrimidine-5-carboxamide as an off white solid. Yield: (180 mg, 28%). MS: m/z 332.1 (ES+, M+H).
