Reaction Steps

In the same manner as described in Example 16, (3S)-1,2,3,4-tetrahydro-β-carboline-3-carboxylic acid (3.24 g), KOH (1.75 g), 70% ethanol (45 ml), carbon disulfide (0.88 ml) and 3,4-dichlorobenzyl chloride (3.52 g) are reacted and treated. The product is purified by silica gel column chromatography (solvent, chloroform:methanol:acetic acid=97:2:1) to give the title compound (3.63 g, 54%), as pale yellow powder.
