Reaction Steps

To 3.0 g (14.0 mmol) of benzenesulfonyl-acetic acid hydrazide in 100 mL of CHCl3, 3.41 g (21.0 mmol, 1.5 eq) of dichloromethylene-dimethyl-ammonium chloride and 3.90 mL (28.0 mmol, 2 eq) of triethyl-amine were added. The solution was stirred at reflux for 1 hour, partitioned between aqueous NaOH 0.5M and EtOAc. The combined organic phases were dried over Na2SO4, filtered, evaporated, and column chromatography on silica gel with CH2Cl2/MeOH 100:1 afforded 0.59 g /15%) of (5-benzenesulfonylmethyl-[1,3,4]oxadiazol-2-yl)-dimethyl-amine as a white solid, MS: 268 (MH+).
