Reaction Steps
A total of 71.4 g of zinc (copper-activated) are added to 118.5 g (0.54 mol) of the compound from Example II in 1000 ml of anhydrous methanol, and the mixture is refluxed for 2 hours. The precipitate is filtered off, and the filtrate is subsequently evaporated in vacuo. Fractional distillation of the residue produces 20.0 g of the title compound having b.p. 96° C./20 mmHg.
