Procedure

A mixture of N-[2-(3-methoxy-phenyl)-4,4-dimethyl-1,2,3,4-tetrahydro-quinoline-6-carbonyl]-methanesulfonamide (1.0 g, 2.95 mmol), sodium hydroxide (0.59 g, 14.75 mmol), water (15 mL) in acetonitrile (30 mL) was stirred at 60° C. for 12 h. The mixture was neutralized with a 3 N aqueous hydrochloric acid solution and extracted with ethyl acetate (2×50 mL), washed with water, dried over anhydrous sodium sulfate and then concentrated in vacuo to afford 2-(3-methoxy-phenyl)-4,4-dimethyl-1,2,3,4-tetrahydro-quinoline-6-carboxylic acid (0.83 g, 90%) as a white solid which was used for next step without further purification: MS (ESI) M+1=312.2.
