Reaction Steps

To a solution of 1.0 gram of 3-[5-(1,1-dimethylethyl)-3-isoxazolyl]-4,5-dihydroxy-1-methyl-2-imidazolidinone in 20 ml. of anhydrous acetone were added three drops of 70% perchloric acid. The reaction mixture stood at ambient temperature for sixteen hours, and then was diluted with 100 ml. of water. The white crystalline precipitate was collected by filtration and recrystallized from diethyl ether and hexane to afford 3-[5-(1,1-dimethylethyl)-3-isoxazolyl]-4,5-dihydroxy-1-methyl-2-imidazolidinone acetonide. M.P. 157°-159° C. Mass Spectrum M+Theory 295; Found 295.
