実験手順
To a solution of niacin (0.4 g 3.50 mmol) in DCM (10 mL) were added L-proline methyl ester (0.5 g, 3.21 mmol), N-methyl morpholine (1.1 mL, 0.10.5 mmol), EDC.HCl (1.2 g, 6.4 mmol) and catalytic amount of DMAP at ice temperature (0° C.). The mixture was allowed to stir at room temperature (25° C.) over a period of 2 h. The resulting mixture diluted with DCM (100 mL) washed with water (2×100 mL) and dried over sodium sulphate. Solvent was evaporated under reduced pressure to obtain product as yellow gummy oil (1.3 g).
