Reaction Steps

To a solution of (±)-(5-chloro-7-thien-3-yl-2,3-dihydro-1-benzofuran-2-yl)methyl 4-methylbenzenesulfonate (4.5 g, 10.69 mmol) in dimethylsulfoxide (150 mL) was added sodium azide (3.6 g, 55.38 mmol) and the reaction mixture was heated to 70° C. and allowed to stir for 6 h. The reaction mixture was cooled to room temperature and diluted with water (300 mL) and diethyl ether (200 mL). The aqueous layer was separated and extracted with diethyl ether (200 mL). The combined organic layers were washed with water (3×200 mL), saturated aqueous sodium chloride (100 mL), dried (magnesium sulfate), and the solvent removed in vacuo to afford 2.6 g (83%) of (±)-2-(azidomethyl)-5-chloro-7-thien-3-yl-2,3-dihydro-1-benzofuran as a white solid. mp 50-52° C.; Anal. calcd. for C13H10ClN3OS: C, 53.52; H, 3.45; N, 14.40. Found: C, 53.50; H, 3.33; N, 14.26.
