Reaction Steps
In the same manner as described in Example 53, ethyl (3R)-1,2,3,4-tetrahydro-β-carboline-3-carboxylate (2.24 g), triethylamine (1.25 g), carbon disulfide (0.76 ml), ethanol (50 ml) and 2-thenyl chloride (1.65 g) are reacted and treated. The product is recrystallized from ethyl acetate-n-hexane to give the title compound (2.60 g, 63%) as colorless needles, m.p. 205°-207° C.
