Reaction Conditions

Reaction Steps

To a solution of 127 mg of 1-{1-[(5-amino-1H-indol-2-yl)carbonyl]piperidin-4-yl}-2-methylpropan-2-ol in 3 mL of methanol were added 90 μl, of 2,5-dimethoxytetrahydrofuran and 1 mL of acetic acid, followed by stirring at 60° C. for 1 day. 1M hydrochloric acid was added to the reaction liquid which was then extracted with ethyl acetate. The organic layer was washed with saturated aqueous sodium chloride solution, dried over anhydrous sodium sulfate, and then concentrated under reduced pressure. The residue was purified by silica gel column chromatography [chloroform:methanol=1:0-10:1], and then solidified from ethyl acetate-hexane to obtain 30 mg of 2-methyl-1-(1-{[5-(1H-pyrrol-1-yl)-1H-indol-2-yl]carbonyl}piperidin-4-yl)propan-2-ol as a white solid.
