Reaction Steps
A mixture of 2.25 g of methyl 3-fluoro-4-(hexadecylamino)benzoate, 280 mg of 1,3-propanediol and 1.37 g. of 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 3-fluoro-4-(hexadecylamino)benzoate.
