Reaction Steps

A mixture of 3,3-dimethyl-2-(3-morpholin-4-yl-phenyl)-1,2,3,4-tetrahydro-quinoline-6-carboxylic acid ethyl ester (5.6 g, 14.2 mmol) in methanol (50 mL) and tetrahydrofuran (100 mL), 30% sodium hydroxide in water (30 mL) was stirred at 60° C. for 6 h. The mixture was neutralized with a 3 N aqueous hydrochloric acid solution and extracted with ethyl acetate (2×100 mL), washed with water, dried over anhydrous sodium sulfate and then concentrated in vacuo to afford 3,3-dimethyl-2-(3-morpholin-4-yl-phenyl)-1,2,3,4-tetrahydro-quinoline-6-carboxylic acid (3.6 g, 69%) as a white solid: LC/MS m/e calcd for C22H26N2O3 (M+H)+: 367.46, observed: 367.1.
