Procedure

A suspension of 1.5 g of 4-methoxymethyl-beta-carboline-3-carboxylic-acid-ethylester, 20 ml of acetonitrile, 3.1 g of sodium iodide and 2.7 ml of trimethylchlorosilane is stirred at 60° C. for 2 h. After cooling, it is poured into ice water and extracted with ethyl acetate. The extracts are washed with saturated sodium thiosulfate solution, dried and concentrated. 1.65 g of 4-iodo-methyl-beta-carboline-3-carboxylic-acid-methylester with a m.p. of 280°-286° C. is obtained.
