Reaction Steps

A mixture of 2,3-dichloro-5-(((2-(trimethylsilyl)ethoxy)methoxy)methyl)pyridine from step (a) above (80 mg, 0.26 mmol), (2R)-1-(4-(3,4-difluorophenyl)-5-(4-(trifluoromethyl)phenyl)-1H-imidazol-2-yl)-2-methylpiperazine (100. mg, 0.236 mmol, Example 1(d)), and DIEA (0.082 mL, 0.47 mmol, Aldrich) in NMP (0.7 mL) was subjected to microwave irradiation at 170° C. for 1 h. The mixture was filtered and the filtrate was concentrated in vacuo. The residue was purified on silica gel using ISCO Combiflash® system with EtOAc/Hexanes (1:9) as the eluant to give the title compound as a light brown solid. MS (ESI, positive ion) m/z: 694 (M+1).
