Reaction Steps

A suspension of (R)-1-(3-bromophenylsulfonyl)-4-(4-fluoro-2-(trifluoromethyl)phenyl)-2-methylpiperazine (168 mg, 0.35 mmol), 1,2-trans-diaminomethylcyclohexane (2.9 mg, 0.015 mmol), K3PO4 (8.5 mmg, 0.06 mmol) and Imidazole (41 mg, 0.6 mmol) in dioxane (0.6 mL) was degassed and heated to 120° C. in a sealed tube till disappearance of starting material as monitored by LCMS. The crude reaction mixture was filtered through a pad of Celite and washed with EtOAc. The crude product was purified on SiO2 column eluted with hexanes/EtOAc to give the desired product as a white solid (123 mg, 75%). HRMS: calcd for C21H20F4N4O2S+H+, 469.13158. found (ESI-FTMS, [M+H]1+), 469.13336.
