Reaction Steps

4-methoxy benzene sulphonyl chloride (495 gm, 2.4 mmol) in dry acetone (5 ml) was added to a stirred solution of dl 1,2,3,4-tetrahydro-9H-pyrido(3,4-b)indole-3-amide (0.430 gm, 1.0 mmol) and dry triethylamine (0.56 ml, 4.0 mmol) in dry DMF (5 ml) during 15 min and was allowed to stirr for 8 hrs. at room temperature (32° C.). Water was added to the reaction mixture and triturated to give 2-[4-methoxybenzenesulfonyl]-1,2,3,4,-tetrahydro-9H-pyrido[3,4-b]indole-3-carboxylic acid amide, which was purified by column chromatography over silica gel using 2% methanol chloroform as eluent. Yield=0.480 gm, (62.34%). m.p.=178-180° C.
