실험 절차
5-(1-tert-Butoxycarbonyl-piperidin-4-yl)-1-(toluene-4-sulfonyl)-1H-indole-2-carboxylic acid ethyl ester (362 mg, 0.687 mmol) was dissolved in a mixture solution of ethyl acetate (4 ml) and 4 M hydrochloric acid/ethyl acetate (8 ml). This was stirred at room temperature under a nitrogen atmosphere for 1.5 hours. The reaction mixture was concentrated under reduced pressure. Thus, 5-piperidin-4-yl-1-(toluene-4-sulfonyl)-1H-indole-2-carboxylic acid ethyl ester hydrochloride was obtained as a colorless amorphous material (332 mg).
