실험 절차

To the suspension of potassium tert-butoxide (1.0 g, 8.91 mmol) in dry THF (10 mL) was added dropwise solution of methyl formate (1.0 ml, 16.22 mmol) and methyl 3-(1H-indol-1-yl)propanoate (1.0 g, 4.92 mmol) in dry THF over 30 min. The mixture was stirred at room temperature for 1 h. Concentration in vacuo then afforded the crude title compound (1.3 g). LCMS: rt=2.59 min, [M+H]=232
