The title compounds were prepared as described for the synthesis of EXAMPLES 57-58 starting from 5-[(1R)-1-hydroxy-2-(piperazin-1-yl)ethyl]-4-methyl-2-benzofuran-1(3H)-one and 5-(oxiran-2-yl)-2,1,3-benzoxadiazole. The resulting two diastereomers were resolved by prep SFC on Chiralcel OJ 30×200 mm column eluting with 70 mL/min of 30% methanol (0.2% DEA)/CO2 at 35° C. with pressure of 100 bar.
