Reaction Steps

A 250 mL round bottom flask equipped with a condenser is charged with ethanol (150 mL), triethylamine (0.93 mL) and diethyl 2-(ethoxy(3-(morpholin-4-ylmethyl)-5,6,7,8-tetrahydroquinolin-8-yl)methyl)malonate (Preparation 17, 750 mg). The solution is heated to reflux. After 12 h, the mixture is concentrated to give a yellow solid, which is purified by flash chromatography (silica gel, 6% MeOH: methylene chloride) to give 603 mg of the title compound. Physical characteristics: 1H NMR (DMSO-d6): δ9.02, 8.04, 7.58, 4.24, 3.59, 3.57, 3.01, 2.88, 2.42, 1.89, 1.30; 13C NMR (DMSO-d6): δ165.3, 154.1, 141.6, 138.3, 134.4, 132.8, 126.9, 125.3, 110.0, 104.3, 66.1, 59.7, 59.1, 52.9, 29.2, 27.8, 20.7, 14.3; IR (KBr) 3079, 3037, 2958, 2931, 2913, 2850, 2828, 1731, 1679, 1647, 1628, 1600, 1509, 1462, 1450, 1297, 1270, 1251, 1227, 1206, 1114, 1097, 1079; HRMS m/z 357.1818.
