Procedure
To a mixture of 3-(4-chlorophenyl)-1-[3-(methylamino)propyl]-1H-naphtho[2,1-b][1,4]thiazin-2(3H)-one (1.79 g), potassium carbonate (2.18 g) and acetone (50 ml) is added allyl bromide (0.65 g) under ice cooling, and the mixture is stirred at room temperature overnight. The insoluble materials are filtered off and acetone is distilled off, and the oily residue is purified by silica gel column chromatography (eluent, chloroform: methanol 20: 1) to give 1-[3-(N-allyl-N-methylamino)propyl]-3-(4-chlorophenyl)-1H-naphtho-[2,1-b][1,4]thiazin-2(3H)-one as oil.
