Participants

Reaction Steps

The title compound was prepared from reaction of 3,4-difluoro-2-[2-fluoro-4-(3-hydroxypropyl)anilino]benzoic acid with 1-[2-(aminooxy)ethoxy]ethylene and DMT-MM by the general procedure of Example 6, Step B, then purified by column chromatography on silica gel (20% EtOAc/PE as eluant) to give 3,4-difluoro-2-[2-fluoro-4-(3-hydroxypropyl)anilino]-N-[2-(vinyloxy)ethoxy]benzamide as a white solid (46%), which was employed directly in the next step. 1H NMR [400 MHz, (CD3)2SO] δ 11.93 (br s, 1 H), 8.79 (br s, 1 H), 7.44-7.38 (m, 1 H), 7.14-7.05 (m, 1 H), 7.04 (dd, J=12.6, 1.6 Hz, 1 H), 6.89 (dd, J=8.2, 1.6 Hz, 1 H), 6.82 (ddd, J=8.7, 8.7, 4.4 Hz, 1 H), 6.50 (dd, J=14.3, 6.7 Hz, 1 H), 4.45 (t, J=5.1 Hz, 1 H), 4.18 (dd, J=14.3, 1.9 Hz, 1 H), 4.06-4.01 (m, 2 H), 3.98 (dd, J=6.6, 1.9 Hz, 1 H), 3.89-3.82 (m, 2 H), 3.42-3.35 (m, 2 H), 2.56 (t, J=7.7 Hz, 2 H), 1.72-1.64 (m, 2 H). LCMS (APCI−) 409 (M−H).
