실험 절차

A solution of methanesulfonamide (106 mg, 1.12 mmol) and trimethyl aluminum (2.0 M in hexanes, 0.56 ml, 1.12 mmol) in dry dichloromethane (5.0 ml) is stirred at room temperature under a nitrogen atmosphere for 20 minutes. A solution of [2-(7-(methoxycarbomethoxy)-1H-indol-3-yl)-1,1-dimethyl-ethyl]-carbamic acid tert-butyl ester (160 mg, 0.425 mmol) in dry dichloromethane (1.5 ml) is added and the mixture is heated under reflux for 15 hours. The mixture is cooled to room temperature and quenched with 1 N HCl solution (3.4 ml) and partitioned between ethyl acetate and water. The organic extracts are dried over anhydrous Na2SO4, filtered and the solvent evaporated to give 220 mg of [2-(7-(methanesulfonamidylcarbomethoxy)-1H-indol-3-yl)-1,1-dimethyl-ethyl]-carbamic acid tert-butyl ester (90%).
