Reaction Steps

To 2-carbomethoxypyrrolidine (d,1-proline methylester, 1.64 g, 12.7 mmol) with pyridine (10.1 g, 12.7 mmol) in CH2Cl2 (100 mL) at 0° C. was added 4-nitrobenzoyl chloride (2.36 g, 12.7 mmol) in CH2Cl2 (25 mL) dropwise. The reaction was allowed to warm to ambient temperature and stirred 18 h. The reaction was evaporated and applied to a silica gel flash column and eluted with a gradient of 2:1 Hexane:EtOAc to 1:2 Hexane:EtOAc. There was isolated 1.3 g of the title compound; LRMS (M+H)+ m/z=279.
