실험 절차

To glacial HOAc (860 mL) was added red fuming HNO3 (300 mL) with cooling and stirring, at such a rate that the temperature was kept below 20° C. This stirred mixture was cooled in an ice bath and the foregoing material prepared in Example 134 (200 g, 78% pure, 1.1 mol) was added in portions over a period of 1 hr such that the temperature was maintained between 18°-20° C. The reaction was then stirred overnight. The precipitate which formed was filtered off and washed with HOAc (50 mL). This solid was then slurried with ice-H2O (400 mL), filtered off and dried to constant weight in vacuo at 60° C. to yield 141 g (0.75 mol, 68% yield) of the title compound; nmr (d6 -DMSO) d: 3.95 (s); mass spectrum showed m/e 187 (M+). A separate synthesis gave an analytical sample.
