실험 절차

To a cooled (0° C.) solution of 7-benzyloxy-6-bromo-2-methyl-4-pyrrolidin-1-yl-quinoline (2.3 g, 5.79 mmol) in dichloromethane (70 mL) was added a 1M solution of titanium tetrachloride in dichloromethane (48.6 mL, 48.6 mmol) within 20 min. After 1 h, the reaction mixture was poured onto an aqueous solution of sodium hydrogenocarbonate, extracted with dichloromethane and evaporated. 1.13 g of the title compound was obtained. Yellow solid, ISP-MS: m/e=308.1 ([M+H]+).
