Procedure

In the same manner as described in Example 53, ethyl (3S)-1,2,3,4-tetrahydro-β-carboline-3-carboxylate (2.24 g), triethylamine (1.20 g), carbon disulfide (0.73 ml), ethanol (50 ml) and 2-thenyl chloride (1.59 g) are reacted and treated. The product is recrystallized from ethyl acetate-n-hexane to give the title compound (2.57 g, 62%) as colorless needles, m.p. 206°-207° C.
