Procedure

To a solution of 5-(5-chloro-2,3-dihydrobenzo[3,4-b]furan-6-yl)-2-pyridylamine (151) (15 mg, 0.06 mmol) in 1 ml DCM was added 2-fluorobenzoyl chloride (11 μl, 0.088 mmol) followed by addition of DIEA (52 μl). The resulting solution was stirred at r.t. for overnight. The reaction mixture was worked up with aq. NaHCO3/DCM. DCM phase was washed with brine, concentrated to dryness. The residue was dissolved in 1 ml THF/MeOH/H2O (5:4:1) and stirred with 1N NaOH (120 μl) at r.t. for 2 h and before worked up with EA/aq. NaHCO3. Silica gel flash chromatography furnished N-[5-(5-chloro(2,3-dihydrobenzo[3,4-b]furan-6-yl))(2-pyridyl)](2-fluorophenyl)carboxamide (153) (14.7 mg, yield: 66.4%, purity>90%) as white solid.
