実験手順
Following the procedure of Example 6, 2-fluoro-4-chloroaniline is reacted with m-phenoxy-α-cyanobenzyl α-bromoisovalerate to give the m-phenoxy-α-cyanobenzyl ester of N-(2-fluoro-4-chlorophenyl)valine, MS m/e 452 (M+). Alternatively 2-fluoro-4-chloroaniline is reacted with the sodium salt of α-bromoisovaleric acid to give N-(2-fluoro-4-chlorophenyl)valine, which is then esterified using m-phenoxy-α-cyanobenzyl bromide or mesylate.
