Reaction Steps
A mixture of (R)-6-(4-fluorophenyl)-6-(3-hydroxypropyl)-3-((S)-piperidin-3-yl)-1,3-oxazinan-2-one (100 mg, 0.30 mmol), 2-bromo-5-(trifluoromethyl)pyridine (67 mg, 0.36 mmol), and triethylamine (91 mg, 0.90 mmol) in acetonitrile was heated to reflux for 3 h. The reaction mixture was concentrated. The residue was purified by preparative TLC and preparative HPLC to afford (R)-6-(4-fluorophenyl)-6-(3-hydroxypropyl)-3-((S)-1-(5-(trifluoromethyl)pyridin-2-yl) piperidin-3-yl)-1,3-oxazinan-2-one (10.09 mg, 7%). LC-MS Method 2 tR=1.34 min, m/z=482. 1H NMR (400MHz, CDCl3): 1.28 (m, 1H), 1.64 (m, 2H), 1.76 (m, 3H), 1.92 (m, 2H), 2.18 (m, 1H), 2.27 (m, 1H), 2.77 (m, 3H), 3.21 (m, 1H), 3.52 (t, 2H), 3.83 (broad, 1H), 4.11 (d, 1H), 4.25 (d, 1H), 6.57 (d, 1H), 7.03 (t, 2H), 7.23 (m, 2H), 7.54 (d, 1H), 8.29 (s, 1H).
