Procedure
A suspension of ((R)-3-Amino-piperidin-1-yl)-[5-(4-methyl-5-trifluoromethyl-isoxazol-3-yl)-thiophen-2-yl]-methanone, hydrochloride (Example 27, 79 mg, 0.2 mmol) in THF (2 mL) was treated with triethylamine (63 μL, 0.45 mmol) followed by methanesulfonyl chloride (19 μL, 0.24 mmol). The reaction mixture was allowed to stir 48 h, evaporated, and chromatographed on silica gel with EtOAc as eluant to afford product as a colorless foam (61 mg, 70%). 1H NMR (CDCl3) 1.68 (m, 2 H), 1.88 (m, 2 H), 2.02 (m, 1 H), 2.33 (d, J=1.8, 3 H), 2.98 (s, 3 H), 3.46 (m, 2 H), 3.57 (m, 1 H), 3.84 (m, 1 H), 4.05 (d, J=12.7, 1 H), 5.45 (d, J=7.5, 1 H), 7.39 (d, J=4.0, 1 H), 7.43 (d, J=3.5, 1 H). 13C NMR 7.9, 23.4, 31.6, 41.9, 47 (br), 52 (br), 49.9, 114.8, 118.7 (q, J=271), 128.2, 129.8, 131.8, 139.6, 155.2 (q, 40), 157.9, 163.5. 19F NMR −63.1. LC/MS 5.82 min, [M+1]+ 438.
