Procedure
Following the procedure of Example 17, N-(2-fluoro-4-chlorophenyl)valine (0.79 g) is reacted with α-ethynyl-m-phenoxybenzyl bromide (0.39 g) to yield the α-ethynyl-m-phenoxybenzyl ester of N-(2-fluoro-4-chlorophenyl)valine, MS m/e 451 (M+). N-(2-fluoro-4-chlorophenyl)valine is prepared from 2-fluoro-4-chloroaniline and α-bromoisovaleric acid using the procedure of Example 17.
