2-[(1S)-6-(1,1-Dioxido-2-isothiazolidinyl)-3,4-dihydro-1H-2-benzopyran-1-yl]ethanol was reacted with methanesulfonyl chloride, as described for the preparation of 2-[(1S)-6-(aminocarbonyl)-3,4-dihydro-1H-2-benzopyran-1-yl]ethyl methanesulfonate. The resultant crude mesylate was then condensed with (3R)-1-(1,2-dihydro-5-acenaphthylenyl)-3-methylpiperazine, as described for Example 1b), to yield the title compound. M+H=532.
