Reaction Steps

A mixture of 2-(3-cyano-phenyl)-4,4-dimethyl-1,2,3,4-tetrahydro-quinoline-6-carboxylic acid ethyl ester (3.0 g, 7.96 mmol), sodium hydroxide (1.8 g, 44.9 mmol), water (15 mL) in acetonitrile (30 mL) was stirred at 60° C. for 4 h. The mixture was neutralized with a 3 mol/L 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-cyano-phenyl)-4,4-dimethyl-1,2,3,4-tetrahydro-quinoline-6-carboxylic acid (1.65 g, 60%) as a white solid which was used for next step without further purification: MS (ESI) M+1=307.2.
