実験手順

A mixture of 3-((4-(4-amino-3-fluorobenzoyl)piperazin-1-yl)methyl)-N-(3,3-difluorocyclobutyl)benzamide (0.224 mmol, 0.1 g) and N-ethyl-N-isopropylpropan-2-amine (0.672 mmol, 0.111 mL, 0.087 g) in dichloromethane were added dropwise to a stirred solution of bis(trichloromethyl) carbonate (0.083 mmol, 0.025 g) in dichloromethane (10 mL). The reaction mixture was allowed to stir for 30 minutes at room temperature. Cyclopropylmethylamine (0.448 mmol, 0.039 mL, 0.032 g) was added and the reaction mixture allowed to stir for a further 2 hours. The reaction mixture was washed with water and the organic phase was concentrated under vacuum. The resulting residue was purified by acidic reverse phase HPLC and converted to the free base to afford the title compound (28 mg). MS (ESI) m/z 544.5 [M+H]+
