Procedure
A solution of 2-butyl-1,2,4-thiadiazolo[4,5-α]benzimidazole-3(2H)-one (15 g, 60.65 mmol) and bromoacetonitrile (18.19 g, 151.6 mmol) in dichloromethane (150 mL) was stirred for 48 h. A white precipitate was formed and the insoluble solid was filtered to give 12.50 g (77%) of the title compound: 1H NMR (CDCl3) δ 4.79 (s, 2H, CH2), 7.42 (t, 1H, ArH), 7.51 (t, 1H, ArH), 7.84 (d, 1H, ArH), 7.94 (d, 1H, ArH); mp 242-244° C.
