3-{[(1S)-1-(2-Hydroxyethyl)-3,4-dihydro-1H-2-benzopyran-6-yl]methyl}-1,3-oxazolidin-2-one 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-(6-cyano-1-naphthyl)-3-methylpiperazine, as described for Example 1b), to yield the title compound. M+H=511.
