Reaction Steps

A mixture of 3,5-dimethoxyaniline (2.1 g), the m-phenoxybenzyl ester of α-bromoisovaleric acid (1.0 g), potassium iodide (72.9 mg) and 5 ml of HMPT is heated overnight at 70°-80°. The reaction is then worked up by partition between 100 ml of 2 N sulfuric acid and 100 ml of ether. The aqueous phase is extracted with ether and then the combined ether phases are washed with 2 N sulfuric acid, saturated sodium bicarbonate and brine, dried over potassium carbonate, filtered and evaporated. The residue is subjected to prep. TLC eluting with ether/hexane to yield the m-phenoxybenzyl ester of N-(3,5-dimethoxyphenyl)valine. MS m/e 435.2 (M+, 11.7), 208.1 (100).
