Procedure

A method similar to that used for the preparation of (107b) was used except that methyl N-[(3,5-difluorophenyl)acetyl]-L-leucinate (108a) (280 mg) was used instead of methyl N-[(3,5-difluorophenyl)acetyl]-L-valinate to afford the desired product (216 mg ). 1H NMR (300 MHz, CDCl3) δ 0.83 (d, 3, J=6 Hz), 0.89 (d, 3H, J=6 Hz), 1.51(m, 3H),3.52 (s, 2H), 4.22 (m, 1H), 7.07 (m, 3H), 8.41 (d, 1H, J=8 Hz), 12.54 (s, 1H).
