Procedure
30 mg of sodium is dissolved in 15 ml of absolute methanol. Then, 300 mg of 4-methoxymethyl-beta-carboline-3-carboxylic-acid-ethylester is added and the mixture is heated with reflux for 2 h. The cooled solution is poured into a sodium dihydrogen phosphate solution and extracted with ethyl acetate. Crystallization in hexane/methylene-chloride yields 270 mg of 4-methoxymethyl-beta-carboline-3-carboxylic-acid-methylester with a m.p. 134°-135° C.
