Participants

Reaction Steps

A stirred mixture of (R)-2-(3-hydroxypyrrolidin-1-yl)-N3-(prop-2-yn-1-yl)-N5-(4-(trifluoromethoxy)phenyl)pyridine-3,5-dicarboxamide (Stage 72.2, 0.50 g, 1.115 mmol) and 4-methoxybenzylamine (0.175 mL, 1.338 mmol) in toluene (30 mL) was treated with zinc trifluoromethanesulphonate (61 mg, 0.17 mmol) and heated under reflux for 41 h. The solvent was evaporated off under reduced pressure and the crude product was purified by flash chromatography (RediSep® Silica gel column, EtOAc 100%) to afford the title compound as a foam. HPLC (Condition 4) tR=4.66 min, UPLC-MS (Condition 8) tR=0.93 min, m/z=568.1 [M+H]+; 1H-NMR (600 MHz, DMSO-d6) δ ppm 1.72 (br. s, 1H), 2.19 (s, 3H), 2.74-3.09 (m, 2H), 2.85-3.07 (m, 1H), 3.15-3.31 (m, 2H), 3.64 (s, 3H), 4.15 (br. s, 1H), 4.90 (m, 3H), 6.72-6.86 (m, 5H), 7.35 (d, J=8.59 Hz, 2H), 7.85 (d, J=8.42 Hz, 2H), 7.19-8.03 (m, 1H), 8.78 (br. s, 1H), 10.05-10.20 (m, 1H).
