Procedure
300 mg (0.71 mmol) of the compound of step 4 and 175 mg (1.07 mmol) of 3-ethanesulfonylphenylboronic acid were dissolved in 4 ml of DMF and 4 ml of 1,2-dimethoxyethane under an argon atmosphere. 216 mg (1.42 mmol) of cesium fluoride and 41.08 mg (0.04 mmol) of tetrakis(triphenylphosphine)palladium(0) were added, and the mixture was heated to 130° C. in a microwave reactor for 15 min. After cooling, the solvent was evaporated and the residue purified by preparative RP HPLC (water/ACN gradient) to yield the methyl ester of the title compound. 135.1 mg (0.26 mmol) methyl ester were dissolved in 5 ml of a mixture of THF and water (9:1), 12.65 mg (0.53 mmol) of lithium hydroxide were added and the mixture was stirred for 3 days. The solvent was evaporated and the residue was purified by preparative RP HPLC (water/ACN gradient). 123 mg of the title compound were obtained.
