19 g of (IV) and 14.5 g of allyl bromide in 200 ml of glacial acetic acid were refluxed for 5 hours, the mixture was cooled, and the liquid product which separated out was triturated with ethyl acetate. The product which crystallized out was filtered off under suction, washed with ethyl acetate and dried under reduced pressure. 14 g of (V) of melting point 109° C. were obtained (compound No. 3a).
