Zinc bromide (160 mg) was added to a solution of tert-butyl(2R)-2-[(cyclopropyl{[5-fluoro-1-(3-methoxypropyl)-1H-indol-6-yl]methyl}amino)carbonyl]morpholin-4-carboxylate (150 mg) in dichloromethane (3 ml) and the mixture was stirred at room temperature for 10 hours. A saturated aqueous solution of sodium bicarbonate was added to the reaction mixture under ice-cooling, and the mixture was extracted with chloroform. The organic layer was washed with saturated brine, dried over magnesium sulfate and concentrated in vacuo. The resulted residue was purified with HPLC MS to give (2R)—N-cyclopropyl-N-{[5-fluoro-1-(3-methoxypropyl)-1H-indol-6-yl]methyl}morpholin-2-carboxamide (50 mg) and (2R)—N-{[3-tert-butyl-5-fluoro-1-methoxypropyl)-1H-indol-6-yl]methyl}-N-cyclopropylmorpholin-2-carboxamide (50 mg) as a colorless oil.
