57% | With triethylamine; In dichloromethane; for 16h; | 2,8-Diazaspiro[4.5]decan-1 -one hydrogen chloride (240 mg, 1.259 mmol) was dissolved in dichloromethane (10 mL) and triethylamine (0.526 mL, 3.78 mmol), and 2-chloro-4-(trifluoromethyl)benzenesulfonyl chloride (457 mg, 1.636 mmol) was added. After stirring for 16 h, the reaction mixture was washed sequentially with aqueous 0.5 M HCI and 0.5 M NaOH, the organic layer was passed through a hydrophobic frit, and concentrated in vacuo. The resulting residue was recrystallised from methanol to give 8-[2-chloro-4-(trifluoromethyl)phenyl]sulfonyl}-2,8- diazaspiro[4.5]decan-1 -one (300 mg, 0.718 mmol, 57% yield) as a white solid. 1 H NMR (250 MHz, DMSO-d6) delta ppm 1 .38 - 1.49 (m, 2 H) 1.65 (ddd, J=13.38, 10.87, 4.22 Hz, 2 H) 1 .91 (t, J=6.83 Hz, 2 H) 2.96 - 3.09 (m, 2 H) 3.14 (t, J=6.81 Hz, 2 H) 3.65 (dt, J=12.99, 4.21 Hz, 2 H) 7.61 (s, 1 H) 7.94 (ddd, J=8.27, 1 .82, 0.62 Hz, 1 H) 8.14 - 8.22 (m, 2 H).
