실험 절차

To a solution of 4-methyl-2-{6-[(E)-2-(4-trifluoromethyl-phenyl)-vinyl]-pyrazin-2-yl}-thiazole-5-carboxylic acid benzylamide (40 mg, 0.08 mmol, 1.0 equiv) in ethyl acetate/ethanol (1:1) was added Pd(OH)2 (10 mg, 20%). The flask was first purged with nitrogen, then with hydrogen. The reaction mixture was stirred at ambient temperature for 3 hr and monitored by LCMS. Upon completion, the reaction mixture was diluted with ethyl acetate, filtered through Celite and concentrated in vacuo. The crude product was purified by preparative HPLC (acetonitrile/water, 0.1% trifluoroacetic acid) to afford 4-methyl-2-{6-[2-(4-trifluoromethyl-phenyl)-ethyl]-pyrazin-2-yl}-thiazole-5-carboxylic acid benzylamide (20 mg, 50%). 1H NMR (400 MHz, CD2Cl2) δ 9.16 (s, 1H), 8.39 (s, 1H), 7.52 (d, J=8.0 Hz, 2H), 7.28-7.37 (m, 7H), 6.25 (bs, 1H), 4.60 (d, J=8.0 Hz, 2H), 3.19 (apparent s, 4H), 2.72 (s, 3H); HRMS (M+H)+=483.14.
