Procedure

To a solution of the compound of Example 223 (0.199 g, 0.7 mmol) in methanol (5 mL) at 0° C. was added nitromethane (0.3 mL, 5.0 mmol) and 2.5 N NaOH (2.3 mL, 5.8 mmol) portionwise over 2 h. The suspension was dissolved by addition of ice-cold water and cold 2N HCl (10 mL) was added. The precipitate was filtered and washed with water to afford the crude title compound. The crude product was purified by recrystallization from aq methanol to afford the title compound as a light yellow fluffy solid (60 mg, 26%). m.p. 104°-106° C.
