Procedure
14.1 g of the compound from (e), 10.7 g of ethyl orthoformate and 12.3 g of acetic anhydride are boiled for 2 hours. The volatile components are then removed by distillation first in a water-pump vacuum and then in a high vacuum at a bath temperature of 130° C. 14 g of the title compound remain (oil).
