A reaction mixture comprising 2.8 g. of the product of Step A above, 30 ml. of acetic anhydride and 2 ml. of acetyl chloride, was heated on a steambath for 6 hours. The reaction mixture was then cooled and poured into ice water, giving a gummy solid after about 15 minutes. The product was filtered and air dried to yield 1.1 g. This was recrystallized from toluene to yield 0.65 g., m.p. 103°-105° C.
