Conditions

Temperature: 130 °C

Procedure

A mixture of 4-(dihydroxyboranyl)benzoic acid (30 mg, 0.181 mmol), (cis)-1-acetyl-6-bromo-2-ethyl-N-phenyl-1,2,3,4-tetrahydro-4-quinolinamine (for a preparation see intermediate 90) (40 mg, 0.107 mmol) and tetrakis(triphenylphosphine)palladium(0) (15 mg, 0.013 mmol) in 1,4-dioxane (1 mL) and water (0.5 mL) was treated with potassium carbonate (45 mg, 0.326 mmol) and the resulting mixture was stirred at 130° C. for 15 min under microwave irradiation then cooled to room temperature and concentrated in vacuo. Purification of the residue by MDAP (modifier: formic acid) gave 4-[(cis)-1-acetyl-2-ethyl-4-(phenylamino)-1,2,3,4-tetrahydro-6-quinolinyl]benzoic acid (20 mg, 0.048 mmol, 45%)
