Reaction Conditions

Reaction Steps

A mixture of 5-chloromethyl-indole-1-carboxylic acid tert-butyl ester (0.41 g, 1.55 mmol, 1.0 eq.), cyclohexanol (0.82 mL, 5.0 eq.) and Ag2O (1.80 g, 5.0 eq.) in diethyl ether (5 mL) was stirred at 35° C. over weekend. After cooling to room temperature, the reaction mixture was filtered through celite washing with ether. The filtrate was concentrated and the residue was purified by chromatography (3% EtOAc/hexanes) to give N-Boc-5-cyclohexyloxymethylindole (160 mg, 28%) as colorless oil. 1HNMR confirmed the compound.
