Procedure
2.7 g (0.01 mole) of the 7-ethyl-7-(3-hydroxyphenyl)-4-methyl-hexahydro-1,4-oxazepine hydrochloride obtained as described in Example 2 are boiled with 25 ml of acetic anhydride for 3 hours. The excess acetic anhydride is then distilled off under reduced pressure and the residue is recrystallized from an isopropanol/ether mixture.
