N-(2-fluoro-4-chlorophenyl)valine and m-phenoxybenzyl bromide are reacted using the process of Example 42 to yield the m-phenoxybenzyl ester of N-(2-fluoro-4-chlorophenyl)valine, MS m/e 427.1 (M+, 4.1), 200 (100). N-(2-fluoro-4-chlorophenyl)-valine is prepared by heating the potassium salt of α-bromoisovaleric acid and 2-fluoro-4-chloroaniline neat at 130° for about 2 hours.
