Procedure
Prepared from 3-t-butoxycarbonylamino-3-methylbutanoic acid (Example 31, Step E) and the amine obtained in Step E by the procedure described in Example 1, Step F. 1H NMR (200MHz, CDCl3): 1.33 (s,6H), 1.42 (s,9H), 1.80(m,1H), 2.24 (m,2H), 2.50 (m,3H), 4.45 (m,1H), 6.98 (d,8Hz,1H), 7.35 (d,2Hz,1H), 7.43 (dd;2,8Hz;1H). FAB-MS: calculated for C20H28IN3O4 501; found 502 (M+H,20%).
