Procedure

To a stirred mixture solution of 4,4-dimethyl-2-(3-morpholin-4-yl-phenyl)-1,2,3,4-tetrahydro-quinoline-8-carboxylic acid methyl ester (380.0 mg, 1.0 mmol) in methanol (10.0 mL) and tetrahydrofuran (10.0 mL) was added 50% sodium hydroxide in water (1.5 mL). The reaction mixture was stirred at 70° 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 4,4-dimethyl-2-(3-morpholin-4-yl-phenyl)-1,2,3,4-tetrahydro-quinoline-8-carboxylic acid (330.0 mg, 90%) as a light white solid which was used for next step without further purification: MS (ESI) M+1=367.1.
