반응 단계
A mixture of 67.5 g (0.29 mol) of the compound of Example 15 and 34.3 g (0.29 mol) of methyl nitroacetate in 540 ml of acetic anhydride was heated at 60° for 2 hours. The product was worked up and recrystallized from benzene-DMF (3:1) affording 75.1 g (78%) of product as red orange crystals, m.p. 213°-215°.
