Procedure

To a solution of 5-amino-N-[2-(aminomethyl)-3,3,3-trifluoro-2-hydroxypropyl]-1-(4-fluorophenyl)-1H-pyrazole-4-carboxamide (250 mg, 0.69 mmol) in tetrahydrofuran (2 ml) was added 2-bromo-6-chlorobenzoyl chloride (192.7 mg, 0.76 mmol) followed by diisopropylethylamine (178 mg, 1.38 mmol). The reaction was left stirring under nitrogen overnight. LC-MS analysis showed the reaction was complete. The reaction mixture was concentrated in vacuo. The residue was redissolved in dichloromethane and washed with 2M hydrochloric acid followed by water. The organic layer was concentrated in vacuo to give the title compound (280 mg).
