To a 50 mL dried round bottom flask containing a degassed solution of 4-phenyl-1-oxa-3-azaspiro[4.5]decan-2-one (1 eq., 1.73 mmol) and 4-iodo-N-(quinolin-8-yl)benzamide (1.2 eq.) in DMF (15 mL), potassium carbonate (2.5 eq.) and trans (N,N)-dimethyl cyclohexanediamine (0.5 eq.), was added CuI (0.1 eq). The resulting mixture was then stirred at 120° C. for 15 hours. Reaction progress was monitored by TLC (TLC eluent: 10% MeOH in DCM). The reaction mixture was cooled and poured into crushed ice (5 g). The solid thus obtained was filtered, washed with water (25 mL) and dissolved in DCM. The DCM solution was then washed with water (100 mL), brine (50 mL) and dried over anhydrous Na2SO4, filtered, concentrated and purified by column chromatography using silica gel and DCM as eluting solvent to yield (R+S) 4-(2-oxo-4-phenyl-1-oxa-3-azaspiro[4.5]decan-3-yl)-N-(quinolin-8-yl)benzamide (90 mg, 11%) as a white solid. 1H NMR (400 MHz, DMSO-d6) δ: 10.46 (s, 1H), 8.95 (dd, J=4.4, 1.6 Hz, 1H), 8.66 (d, J=6.4 Hz, 1H), 8.44 (dd, J=8.4, 1.6 Hz, 1H), 7.94 (d, J=8.0 Hz, 2H), 7.75-7.72 (m, 3H), 7.68-7.61 (m, 3H), 7.32-7.39 (m, 4H), 5.52 (s, 1H), 2.08-2.11 (m, 1H), 1.83-1.89 (m, 1H), 1.74-1.53 (m, 3H), 1.35-1.42 (m, 2H), 1.20-1.23 (m, 3H). m/z (ESI) 478.2 (M+H)+.
