Procedure

250 mg (0.62 mmol) of the compound of example 194, step 1, and 152.1 mg (0.93 mmol) of 3-isopropylphenylboronic acid were dissolved in 5 ml of DMF and 5 ml of toluene under an argon atmosphere. 187.9 mg (1.24 mmol) of cesium fluoride and 35.73 mg (0.05 mmol) of tetrakis(triphenylphosphine)palladium(0) were added, and the mixture was stirred overnight at 100° C. After cooling, the mixture was filtered and the solvent was evaporated. The obtained 2-[(3′-isopropyl-6-methoxy-biphenyl-3-carbonyl)-amino]-indane-2-carboxylic acid methyl ester was dissolved in 10 ml of a mixture of THF and water (9:1), 42.2 mg (1.80 mmol) of lithium hydroxide were added and the mixture was stirred overnight. The solvent was evaporated and the residue was purified by preparative RP HPLC (water/ACN gradient). 71 mg of the title compound were obtained.
