6.60 g (16.2 mmol) N-(3-acetyl-5-benzyloxy-2-hydroxy-phenyl)-2-bromo-2-methyl-propionamide and 2.76 g (20 mmol) potassium carbonate are stirred for 1 hour in 70 mL acetonitrile at reflux temperature. The solid is suction filtered, the filtrate is evaporated down and the residue is combined with 30 mL ethyl acetate. After further filtration and elimination of the solvent by distillation the crude product is crystallised from a little methanol.
