Heating an ethanol solution of 2-imino-2-(1,2,2,5,5-pentamethyl-3-oxide-2,5-dihydro-1H-imidazol-4-yl)-1-phenylethanone in the presence of triethylamine yielded 3-hydroxy-5,5,6,7,7-pentamethyl-3-phenyl-3,5,6,7-tetrahydroisoxazolo[4,3-d]pyrimidine, whose structure was determined by single crystal X-ray diffraction.
