Procedure
A mixture of N-(3-allyloxyphenyl)acetamide (13.2 g) prepared by a similar method to that of Example 2, Footnote c (A), from N-(3-hydroxyphenyl)acetamide, in Ph2O (100 ml) was heated at 250° C. for 10 minutes, cooled and diluted with hexane (100 ml) to give crystals. The crystals were re-crystallised from ethyl acetate. The liquors were evaporated and dissolved in 0.2M aqueous NaOH, filtered though Celite, and acidified with 1M aqueous HCl solution to give N-(4-allyl-3- hydroxyphenyl)acetamide (3.6 g) mpt. 164°-165° C.
