Participants

Reaction Steps

To a solution of zinc chloride (28 mg, 0.149 mmol) and 4-[5-cyano-6-(2-fluoro-4-methanesulfonyl-phenylamino)-pyrimidin-4-yloxy]-piperidine-1-carboxylic acid isopropyl ester (1 g, 2.09 mmol) in chlorobenzene (15 mL), ethane-1,2-diamine (0.100 mL, 1.463 mmol) was added. The mixture was heated under reflux for 24 h. LCMS indicated desired product. The crude was concentrated under vacuo and purified by HPLC to afford compound A92 as a yellow solid (303 mg, 23%). 1H NMR (CDCl3, 400 MHz) δ 1.23 (d, 6H), 1.68-1.77 (m, 2H), 2.05-2.09 (m, 2H), 3.07 (s, 3H), 3.16-3.23 (m, 2H), 3.84-3.92 (m, 2H), 4.07 (s, 4H), 4.87-4.92 (m, 1H), 5.42-5.47 (m, 1H), 7.50-7.62 (m, 2H), 7.79-7.83 (m, 1H), 8.35 (s, 1H). Exact mass calculated for C23H29FN6O5S 520.19, found 521.5 (MH+).
