실험 절차
To a 0° C. solution of methyl 1-isopropyl-1H-indole-6-carboxylate (0.50 g, 2.30 mmol) in THF (5 mL) was added 1M lithium borohydride in THF (6.90 mL, 6.90 mmol). After stirring at rt for 96 h, quenched with MeOH and let stir for 1 h. The reaction mixture was concentrated, partitioned between saturated sodium bicarbonate and EtOAc, washed with H2O and brine, dried with Na2SO4, and concentrated. The crude compound was chromatographed to give the desired product.
