Reaction Steps

A mixed solution of 3-(1-acetyl-4-piperidinyl)-1-(1,2,2a,3,4,5-hexahydrobenz[cd]indol-6-yl)-1-propanone (free base, 0.15 g, 0.44 mmol) and acetic anhydride (0.066 ml, 0.69 mmol) in ethyl acetate (20 ml) was heated at 70-75° C. with stirring for 1 hour. The solvent was then distilled off and the residue was purified by silica gel column chromatography (eluent: ethyl acetate-methanol=20:1) to provide the title compound (0.155 g) as colorless crystals melting at 130-132° C.
