Procedure

In the same manner as described in Example 53, ethyl (3R)-1,2,3,4-tetrahydro-β-carboline-3-carboxylate (224 mg), triethylamine (120 mg), carbon disulfide (0.08 ml), ethanol (25 ml) and methyl iodide (0.08 ml) are reacted and treated. The product is crystallized from ether to give the title compound (140 mg) as colorless prisms, m.p. 139°-141° C.
