Procedure

A solution of 5.0 g (0.012 mole) of 3,5-bis(1,1-dimethylethyl)-N-[(ethoxycarbonyl)oxy]-4-[(2-methoxyethoxy)methoxy]benzenecarboximidamide in toluene (150 ml) is stirred at 120°-130° C. for 18 hours. The toluene is evaporated (vacuum) and the residual oil solidifies upon standing. The solid is recrystallized from ethyl acetate and hexane giving 3.1 g (70%) of analytically pure 3-[3,5-bis(1,1-dimethylethyl)-4-[(2-methoxyethoxy)methoxy]phenyl]-1,2,4-oxadiazol-5(4H)-one, mp 112°-114° C.
