    摘要: 1,2,3,9-tetrahydro-9-methyl-3-[(2-methyl-1H-imidazol-1-yl)methyl]-4H-carbazol-4-one or its salt is prepared in high yield by reacting a compound of formula 2 with a compound of formula 3 and a compound of formula 4 in the presence of an acid, an alkylsilylhalide compound or an acylhalide compound, in an solvent, and thus, such an inventive process can be favorably applied to a large-scale mass production thereof.
