Procedure

To a mixture of 3.0 gms of the product from Step A in 25 ml of isopropyl alcohol was added 1.0 ml of hydrazine hydrate and the mixture was refluxed under nitrogen overnight. The reaction was then cooled to 0° C. and filtered and the solids were washed with water and then cold isopropyl alcohol. This afforded 2.32 g of a white solid, mp 221°-223° C. 1H NMR (CDCl3) δ: 2.80 (d, 1H), 3.05 (dd, 1H), 4.50 (d, 1H), 7.1-7.5 (m, 8H), 7.69 (m, 2H), 8.76 (bs, 1H).
