Reaction Steps

A mixture of 2-((2-(4-(1-acryloylazetidin-3-yl)piperazin-1-yl)-2-oxoethyl)amino)-5-chloro-4-cyclopropylbenzamide (3 0 mg, 0.067 mmol) and Et3N (41 mg, 0.404 mmol) in DCM (10 mL) at RT, trifluoroacetic anhydride (56 mg, 0.268 mmol) was added. The resulting mixture was stirred at RT for 0.5 h, poured into water and then extracted with dichloromethane. The organic layer was washed with brine, dried over Na2SO4 and concentrated. The residue was purified by flash column chromatography on silica gel (1-4% methanol/dichloroethane) to afford the desired product (20 mg, 72% yield). 1H NMR (400 MHz, DMSO-d6) δ: 7.60 (s, 1H), 6.34-6.30 (m, 1H), 6.27 (s, 1H), 6.12-6.07 (m, 1H), 6.01-5.99 (t, J=4 Hz, 1H), 5.69-5.65 (m, 1H), 4.26-4.22 (m, 1H), 4.07-4.04 (m, 3H), 3.96-3.92 (m, 1H), 3.80-3.76 (m, 1H), 3.53-3.51 (m, 4H), 3.19-3.13 (m, 1H), 2.45-2.30 (m, 4H), 2.16-2.09 (m, 1H), 1.08-1.03 (m, 2H), 0.87-0.80 (m, 2H). ESI-MS m/z: 428.4[M+H]+.
