실험 절차

6-tert-Butyl-2,3-dihydro-indole-1-carboxylic acid tert-butyl ester (Prepared in Example HH; 12.0 g) in CH2Cl2 (100 mL) was cooled to 0° C. and treated with HCl gas for 10 minutes. The reaction mixture was warmed to room temperature and stirred for 1 hour. The solvents were evaporated; the residue was dissolved in EtOAc, washed with saturated NaHCO3 solution and brine, and dried (MgSO4.) Concentration gave the title compound which was used without any further purification. MS(APCI): 176 (M+H).
