Reaction Conditions

Reaction Steps

A mixture of 2-{[4-(2-tert-butylphenyl)piperazin-1-yl]carbonyl}-1-methyl-1H-indol-5-ol obtained in Example 28 (510 mg), methyl bromoacetate (239 mg), potassium carbonate (276 mg), and N,N-dimethylformamide (5 mL) was stirred at 60° C. for 3 h. Water was added to the reaction solution, and the mixture was extracted with ethyl acetate. The ethyl acetate layer was washed with saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure to afford crystals. Crystals were washed with diethyl ether and dried under reduced pressure to provide the title compound (509 mg, 84%) as crystals.
