Reaction Steps
0.2 g of 4-methoxymethyl-5-oxo-5,6,7,8-tetrahydro-betacarboline-3-carboxylic acid ethyl ester is refluxed in 10 ml of isopropanol with 0.1 ml of titanium tetraisopropylate for 1.5 hours under argon atmosphere. The crystals precipitated after cooling are sectioned off and rewashed with isopropanol. 0.135 g of 4-methoxymethyl-5-oxo-5,6,7,8 -tetrahydro-beta-carboline-3-carboxylic acid isopropyl ester with a melting point of 243°-245° C. is obtained.
