PyBroP (188 mg, 0.40 mmol) and 1-(3,3-dimethyl-butyl)-piperidine-4-carboxylic acid (82 mg, 0.38 mmol) were added to a solution of 4-aminomethyl-3,N-dimethyl-N-(4-trifluoromethyl-phenyl)-benzamide from Example E118.3 (100 mg, 0.31 mmol) in dichloromethane (5 ml) and DIEA (0.081 ml, 0.46 mmol). The mixture was stirred at room temperature for 2 days, washed with saturated NaHCO3 then brine, dried and concentrated in vacuo. The residue was purified by preparative HPLC (eluant; 0.5% 35% ammonia:9.5% methanol:90% dichloromethane) to give a off-white powder identified as the title compound (22 mg, 14%).
