89% | With ammonium chloride; In ethanol; for 0.75h;Reflux; | General procedure: To asolution of hydrazide (0.73 mmol) in 10 mL of anhydrous ethanol, added triethyl orthoester (0.81 mmol) and ammonium chloride (0.219 mmol). The solution was stirred and heated to reflux until it complete (0.5-18 h). The reaction mass was cooled to room temperature and concentrated under vacuum. The crude product was made into slurry in a mixture of hexanes and ether (3:1), filtered,washed with deionized water or purified by column chromatography. |
84% | at 110℃; for 3.5h; | 210c) 2-(3-Bromophenyl)-5-methyl-1 ,3,4-oxadiazole A solution of 3-bromobenzohydrazide (55.0 mg, 0.256 mmol) and triethyl orthoacetate (1 132 mu, 6.14 mmol) was stirred at 1 10 C for 3.5 h. LCMS showed good conversion. The reaction mixture was concentrated. The crude product was taken up in DCM (~1 mL) and purified on a silica cartridge (12 g) with a Combiflash Companion, eluting at 20 mL/min with a gradient running from 0 % EtOAc / hexanes to 40 % EtOAc / hexanes over 25 min. The desired fractions were concentrated on the rotary evaporator to afford the title compound (51 .1 mg, 0.214 mmol, 84 % yield). LC-MS m/z 240.9 (M+H)+, 0.81 min (ret. time). |
