Procedure

Dry DMF (40 ml.) was cooled in an ice bath to 10°-15° C. Sodium hydride (7.2 g., 0.15 mole) was then added. The suspended mixture was stirred for 10 minutes and acetaldoxime (11.8 g., 0.2 mole) was added portionwise. After stirring for another 10 minutes the compound from Example 1 (17.8 g., 0.05 mole) in 30 ml. dry DMF was added dropwise. When the addition was completed, the ice bath was removed and the reaction mixture was stirred at room temperature for 21/2 hours. The mixture was poured into ice water and was filtered. The filtrate was acidified with concentrated HCl to obtain a precipitate. The crude solid was purified from aqueous ethanol to yield 11 g. (67%), m.p. 169°-170° C.
