(3S,4S)-4-[(S)-3-(4-Fluoro-benzyl)-piperidin-1-ylmethyl]-tetrahydro-pyran-3-ylamine (49 mg, 160 μmol) and (5-acetyl-4-methylthiazol-2-yl)-carbamic acid phenyl ester (49 mg, 176 μmol) were dissolved in acetonitrile (1 mL) and the mixture was stirred at room temperature. After 24 h , the mixture was concentrated, dissolved in ethyl acetate, washed with water, dried (Na2SO4) and concentrated. The residue was purified by reverse phase high pressure liquid chromatography (C18, 10-100% acetonitrile in water, containing 0.05% trifluoroacetic acid), then by flash column chromatography (5% methanol in dichloromethane, containing 0.5% ammonium hydroxide) to provide the product as a glass (18 mg, 23%). 1H NMR (300 mHz, CD3OD) δ7.05 (m, 2H), 6.87 (m, 2H), 3.90 (dd, J=11.0, 4.4 Hz, 1H), 3.84 (m, 1H), 3.53 (td, J=9.5, 4.3 Hz, 1H), 3.40 (bt, 1H), 3.10 (m, 1H), 2.90 (bd, 1H), 2.75 (bd, 1H), 2.58 (s, 3H), 2.48 (s, 3H), 2.45 (m, 3H), 2.21 (dd, J=13.6, 6.3 Hz, 1H), 1.91 (bt, 1H), 1.8-1.5 (7H), 1.37 (m, 1H), 0.92 (m, 1H), ESI MS: (M+H)+=489.4 (100%).
