Procedure

4-Fluoro-naphthalene-1-sulfonyl chloride 27 (10.0 g, 40.9 mmol) was dissolved in THF (100 mL) and stirred at room temperature. 4-Amino-piperidine-1-carboxylic acid tert-butyl ester (8.19 g, 40.9 mmol) and triethylamine (4.14 g, 5.75 mL, 40.9 mmol) were added and the reaction was stirred overnight at room temperature. The solvent was removed in vacuo. Dichloromethane (250 mL) was added and the solution was charged to a separatory funnel. The organic layer was washed twice with water and brine and dried over MgSO4. Filtration and concentration in vacuo afforded 28 as a yellow foam. Wt.: 15.1 g (90%). 1H NMR (300 MHz, CDCl3) δ 8.62 (d, 1H), 8.26 (m, 2H), 7.69 (m, 2H), 7.20 (m, 1H), 4.92 (d, 1H), 3.82 (m, 2H), 3.26 (m, 1H), 2.70 (m, 2H), 1.61 (m, 2H), 1.40 (s, 9H), 1.24 (m, 2H); LC/MS m/z 409 (M+H)+.
