実験手順
The title compound was prepared from 1-(2-hydroxyethyl)-1,3-dihydro-2-benzofuran-5-carboxamide by initial formation of the methanesulfonate as described for the preparation of 2-[(1S)-6-(aminocarbonyl)-3,4-dihydro-1H-2-benzopyran-1-yl]ethyl methanesulfonate, and condensation of this sulfonate with (3R)-1-(1,2-dihydro-5-acenaphthylenyl)-3-methylpiperazine, as described for Example 1b). The mixture of diastereomers was separated by chiral HPLC using a Chiracel OJ column, eluting with hexane/ethanol (1:1) with 0.2% dimethylethylamine. M+H=442.
