Procedure
(R)-(N-Benzyloxycarbonylpyrrolidin-2-ylcarbonyl)-5-methoxy-1H-indole was used. The chromatographic eluent was 8% triethylamine in ethyl acetate to afford the title compound (yields ranged from 13 to 61%) as an oil whose spectral and physical properties were identical with the spectral and physical properties of the title compound of Example 1A with the exception of specific rotation of plane polarized light: [α]25D =+100° (CHCl3, c=1.0). HRMS: calculated for C15H20N2O: 244.1573; found: 244.1547.
