Procedure

To a solution of methyl 10-bromo-9-fluoro-3-(hydroxy(1-methyl-1H-pyrazol-5-yl)methyl)-6,7-dihydro-5H-5,7-methanobenzo[c]imidazo[1,2-a]azepine-2-carboxylate (140 mg, 0.3035 mmol) in dichloromethane (0.91 mL) was added triethylamine (4.0 equiv., 0.171 mL, 1.214 mmol) followed by methanesulfonyl chloride (1.2 equiv., 0.029 mL, 0.3642 mmol). The reaction was stirred at room temperature until LC/MS analysis indicated complete consumption of starting material.
