Procedure

A mixture of 1 g (2.5 mmol) of the compound of step C. above, 0.539 ml (5.48 mmol) of phenylhydrazine, 0.75 ml of conc. hydrochloric acid, and 30 ml of absolute ethanol is stirred under reflux for 6 hrs. The cooled precipitate is dissolved in methanol and treated with a Na2CO3 solution. The precipitate is collected and washed with water to yield 0.388 of a brown solid. Trituration with ether affords 0.303 g (26%) of the title compound as a light brown solid: m.p. 170°-172° C.; IR (KBr) 3320, 1687, and 1604 cm-1 ; NMR (DMSO-d6) δ 9.56 (s, 1H), 8.27 (d, 1H), 8.17 (d, 2H), 8.07 (s, 1H), 7.70 (m, 5H), 7.54 (t, 1H), 6.70 (d, 2H), 4.23 (q, 2H), 3.78 (m, 2H), 3.46 (t, 2H), 1.26 (t, 3H).
