Participants

Reaction Steps

A solution of 3-(3-bromomethyl-4-chloro-phenyl)-5-(3-chlorothiophen-2-yl)-[1,2,4]oxadiazol (0.030 g, 0.077 mmol), pyrrolidine (0.013 mL, 0.16 mmol), Et3N (0.054 mL, 0.39 mmol) and dichloromethane (8.0 mL) was stirred at room temperature for 20 h. The solution was diluted with dichloromethane (30 mL), washed with 10% Na2CO3 (25 mL), dried over Na2SO4, and concentrated. The product was azeotroped with dichloromethane (3×5 mL) and hexanes (2×5 mL) to give 0.028 g (96%) of the title compound as a white solid. 1H NMR (CDCl3): 8.27 (d, 1H, J=1.7 Hz), 7.98 (dd, 1H, J=8.2 and 1.9 Hz), 7.61 (d, 1H, J=5.2 Hz), 7.49 (d, 1H, J=8.5 Hz), 7.13 (d, 1H, J=5.2 Hz), 3.85 (s, 2H), 2.67 (br s, 4H), 1.84 (br s, 4H).
