Procedure

To 20 mg (0.05 mmol) of amine 20-2 in CH2Cl2 was added 21 μL (0.15 mmol) of triethylamine and 5.8 μL (0.10 mmol) of methyl chloroformate. After stirring overnight the reaction was partitioned between EtOAc and 10% KHSO4, the organic phase was washed with saturated NaHCO3, brine, dried over MgSO4, and concentrated by rotary evaporation. The residue was purified by column chromatography on silica gel with EtOAc/hexanes to provide 22-1 as a white solid. Data for 22-1: 1HNMR (500 MHz, d6-DMSO) δ 7.6 (m, 1H), 7.5-7.1 (m, 8H), 6.2 (s, 1H), 4.95 (m, 1H), 4.7 (m, 1H), 3.55 (s, 3H), 3.0 (m, 2H), 2.7 (s, 6H), 2.7-2.5 (m, 1H), 2.05 (m, 1H), 1.4 (m, 2H) ppm. HRMS (ES) calc'd M+H for C24H27ClFN3O3: 460.1798. Found: 460.1797.
