Participants

Reaction Steps

To a solution of 5-(6-chloro-2,3-dihydrobenzo[3,4-b]furan-5-yl)-2-pyridylamine (144) (19 mg, 0.045 mmol) in 1 ml DCM was added 2-fluorobenzoyl chloride (16 μl, 3 eq) followed by addition of DIEA (39 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 (100 μl) at r.t. for 2 h and before worked up with EA/aq. NaHCO3. Prep HPLC purification furnished N-[5-(6-chloro(2,3-dihydrobenzo[3,4-b]furan-5-yl))(2-pyridyl)](2-fluorophenyl)carboxamide (146) (7.6 mg, yield: 45.8%, purity>95%) as white solid.
