After 18 hours at room temperature the reaction mixture was washed successively with water, 5% aqueous citric acid solution, water and saturated brine, dried (MgSO4) and evaporated under reduced pressure to give an oil which was dissolved in the minimum volume of dichloromethane. Treatment of this solution with diisopropyl ether provided the title compound (11.7 g) as a gum. Rf 0.56 (SS 8). m/e 510.
