실험 절차
To m-phenoxy-α-cyanobenzyl α-bromoisovalerate (2.0 g, 0.0052 mole) in 4 ml of HMPT, at 24°, is added aniline (1.5 g, 0.016 mole) and potassium iodide (21 mg). The reaction is stirred at 65° for 90 hours and then cooled and poured into ice-water (20 ml) plus 2 N sulfuric acid (10 ml). The reaction is worked up as in Example 4 and purified by preparative TLC to give the m-phenoxy-α-cyanobenzyl ester of N-phenylvaline.
