Reaction Steps
To 2-chlorobenzoic acid (10 g; 63.9 mmol) in dimethylformamide (100 ml) under nitrogen was added carbonyldiimidazole (10.9 g; 67.1 mmol) and the solution stirred for 1 h at room temperature. (S)-(+)-2-pyrrolidinemethanol (7.56 ml, 76.6 mmol) was added and the mixture stirred at 40° C. for 18 h. The solvent was removed under reduced pressure and the crude product purified by chromatography on silica (eluting with 50% to 75% ethyl acetate in heptane) to afford (S)-1-(2-chlorobenzoyl)-2-pyrrolidinemethanol (10.2 g), which was used directly in the next step.
