실험 절차
A mixture of 6′ chloro-spiro[cyclopropane-1,3′-[3H]indol]-2′(1′H)-one (0.291 g, 1.5 mmol) and borane-dimethyl sulfide complex in THF (2 M, 3.0 mL) was heated at reflux under nitrogen for 2 h. The mixture was cooled and MeOH (3 mL) was added dropwise (caution!). The resulting mixture was heated at reflux for 2 h, then was cooled and solvent evaporated in vacuo. Chromatography (SiO2; gradient elution with 0-100% Et2O in petrol) gave the title compound (0.142 g). MS: [M+H]+=180.
