A mixture of 5-(2,3-dihydro-1-benzofuran-5-yl)-1,3,4-oxadiazole-2-thiol (0.20 g, 0.91 mmol), 3-fluorobenzyl chloride (0.11 mL, 0.91 mmol), 1 M aqueous sodium hydroxide solution (1.00 mL, 1.00 mmol) and water (4 mL) was stirred overnight at room temperature. The precipitate was collected by filtration and recrystallized from hexane/ethyl acetate to give the title compound (0.21 g, yield 74%) as colorless crystals.
