Reaction Steps
To a mixture of 4-(2-bromophenoxy)pyrrolidine hydrochloride (0.5 g, 1.87 mmol) and 5-bromo-1,3,4-thiadiazole-2-carbonitrile (0.36 g, 1.87 mmol) in DMF (10 mL) was added K2CO3 (0.77 g, 5.61 mmol) under a nitrogen atmosphere. The mixture was stirred at 70° C. for 4 h. After dilution with water, the mixture was extracted with ethyl acetate. The combined organic extracts were washed with brine, dried over anhydrous Na2SO4, filtered and purified by preparative TLC with petroleum:EtOAc (2:1) to give the title compound. 1H NMR (300 MHz, CDCl3): δ 7.58 (d, 1H), 7.52 (t, 1H), 7.08 (t, 1H), 6.99 (d, 1H), 5.24 (m, 1H), 3.69-3.93 (m, 4H), 2.33-2.56 (m, 2H).
