Procedure

A mixture of 2.25 g. of methyl 2-(allylamino)phenylacetate, 280 mg. of 1,3-propanediol and 1.37 g. p-toluenesulfonic acid is heated at 180° C. for 18 hours and then is partitioned between ether and 3% aqueous sodium carbonate solution. The ether layer is separated, dried, and evaporated to yield 3-hydroxypropyl 2-(allylamino)phenylacetate.
