PROCEDURE

实验过程

This compound is prepared in a manner analogous to that of Step E of Example 12, using 3.5 grams (0.010 mole) of 2,4-di[(1,1-dimethylethyl)carbonylamino]-5,6,7,8-tetrahydro-6-quinazolinone (prepared in Step C of Example 12) and 2.7 grams (0.012 mole) of O-(3-trifluoromethylphenylmethyl)hydroxylamine hydrochloride in about 45 mL of ethanol. This preparation differs from Step E of Example 12 in that prior to heating at reflux for four hours, 1.5 grams (0.01 5 mole) of triethylamine is added as an acid acceptor, yielding 2,4-di[(1,1-dimethylethyl)carbonylamino]-6-(3-trifluoromethylphenylmethoxyimino)-5,6,7,8-tetrahydroquinazoline.
