Procedure

To a solution of N-(4-(4-oxo-1-phenyl-1,3,8-triazaspiro[4.5]decan-3-yl)phenyl)methanesulfonamide (0.2 g, 0.46 mmol) and potassium carbonate (0.191 g, 1.38 mmol) in N,N-dimethylformamide (5 mL), was added 1-(4-fluorophenyl)-4-iodobutan-1-one (0.134 g, 0.46 mmol). After stirring at 65° C. for 18 hours, the reaction mixture was diluted with ethyl acetate (25 mL), washed with water and brine. The organic phase was dried over MgSO4, filtered, concentrated and isolated by pTLC (10% methanol/dichloromethane) to obtain the product (0.03 g, 12%); 1H NMR (DMSO-d6): δ 1.70-1.90 (m, 4H), 2.40-2.49 (m, 2H), 2.66-2.84 (m, 6H), 2.97 (s, 3H), 3.05 (br, 2H), 5.12 (s, 2H), 6.88 (t, 1H, J=7.6 Hz) 6.99-7.03 (m, 2H), 7.26 (d, 4H, J=9.2 Hz), 7.34 (t, 2H, J=8.4 Hz), 7.76 (d, 2H, J=8.8 Hz), 8.04-8.07 (m, 2H), 9.73 (s, 1H); MS for C30H33FN4O4S m/z 565.3 (M+H)+.
