실험 절차

Phosphorus oxychloride (3.06 g., 0.02 mole) in 10 ml. of 1,2-dichloroethane is added dropwise in 20 min. to a solution of 3-(p-anisidinomethyl)indole (5.04 g., 0.02 mole), 5-methyl-2-pyrrolidinone (1.98 g., 0.02 mole) and triethylamine (2.02 g., 0.02 mole) held at a temperature of about 3° C. When the addition is complete, the mixture is stirred at 3° to 4° C. for 5 hr. and then filtered to provide 2.4 g. solid which is crystallized from water affording 1.02 g., m.p. 184°-187° C. This fraction is combined with an additional 1.81 g. fraction obtained as hereinabove described and crystallized from ethanol to furnish analytically pure 3-[[N-(5-methyl-1-pyrrolin-2-yl)-p-anisidino]methyl]indole hydrochloride, m.p. 181.5°-183.5° C. (corr.)
