Reaction Steps

U1 was prepared from 4-(2-fluoro-4-nitro-phenoxy)-6-methoxy-quinolin-7-ol and tert-butyl 4-(bromomethyl)piperidine-1-carboxylate following the general procedure reported in Preparative Example 54 Step 1-2. 1H NMR (400 MHz, CDCl3, 300K) δ 1.22 (m, 2H), 1.40 (s, 9H), 1.82 (d, J=12.7 Hz, 2H), 2.10 (m, 1H), 2.69 (t, J=12.3 Hz, 2H), 3.77 (m, 2H), 3.96 (s, 3H), 3.97 (m, 2H), 4.10 (m, 2H), 6.31 (d, J=5.2 Hz, 1H), 6.46 (m, 2H), 6.96 (t, J=8.7 Hz, 1H), 7.31 (s, 1H), 7.51 (s, 1H), 8.40 (d, J=5.2 Hz, 1H). MS (ES) C27H32FN3O5 requires: 497. Found: 498 (M+H)+.
