실험 절차
To a solution of (S)-1-isopropylpyrrolidine-2-carboxylic acid (4 g, 23.4 mmol) in dry dichloromethane (40 mL) was added oxalyl chloride (4.4 mL, 46.8 mmol) drop wise under nitrogen at ice bath temperature (0-10° C.). After stirring for 5 min, a drop of dry DMF was added to the reaction mixture and was allowed to stir for 2 h at the same temperature. The volatiles were removed on a rotavapor at reduced pressure and the residue was allowed to stay at high vacuum pump for 1 h to afford (S)-1-isopropylpyrrolidine-2-carbonyl chloride.
