Procedure

A mixture of 63.0 g (0.29 mol) of the compound of Example 14 and 35.7 g (0.30 mol) of methyl nitroacetate in 600 ml. of acetic anhydride was heated at 85° for 2 hours. The resulting product was worked up and recrystallized from benzene-DMF (2:1) affording 74.9 g (81%) of product as red orange crystals, m.p. 211°-214°.
