Reaction Steps

To a solution of (3R)-4-allyl-3-ethyl-3,4-dihydro-8-isopropoxy-10-(trifluoromethyl)-2H-[1,4]oxazino[2,3-f]quinoline (0.24 g, 0.63 mmol) and 0.1 mL Et3N in 3 mL EtOAc was added 10% Pd on carbon (0.08 g) and the mixture was vigorously stirred under H2 atmosphere for 1 h. The reaction mixture was filtered through Celite and concentrated to give 0.23 g (96% yield) of (3R)-3-ethyl-3,4-dihydro-8-isopropoxy-4-propyl-10-(trifluoromethyl)-2H-[1,4]oxazino[2,3-f]quinoline, a yellow oil. Rf0.7 (9:1 hexane:EtOAc); 1H NMR (400 MHz, CDCl3) δ 7.41 (d, 1H, J=9.1), 7.22 (d, 1H, J=9.1), 7.17 (s, 1H), 5.47 (septet, 1H, J=6.2), 4.30 (dd, ABX, 1H, J=10.5, 1.6), 3.86 (dd, ABX, 1H, J=10.5, 2.5), 3.47–3.35 (m, 1H), 3.23–3.11 (m, 2H), 1.70–1.55 (m, 4H), 1.38 (d, 3H, J=6.2), 1.37 (d, 3H, J=6.2), 1.02–0.91 (m, 6H).
