Methyl chloro(oxo)acetate (0.842 mL) was added to a stirred solution of methyl [trans-4-(4-aminophenyl)cyclohexyl]acetate (1740 mg) and pyridine (0.689 mL) in DCM (50 mL) at 0° C. After the addition was complete the mixture was allowed to warm to ambient temperature and stirred for 64 hours. The solution was diluted with DCM (100 mL), washed with water (50 mL) and brine (50 mL), then dried and concentrated in vacuo to give the title compound (2267 mg) as a solid; 1H NMR δ 7.60 (2H, d), 7.18 (2H, d), 3.83 (3H, s), 3.58 (3H, s), 2.58-35 (1H+DMSO, m), 2.21 (2H, d), 1.75 (5H, m), 1.43 (2H, m), 1.12 (2H, m); MS m/e MH− 332.
