Reaction Steps

A stirred solution of 4-{[(4′-difluoromethoxy-biphenyl-4-yl)-methyl-amino]-methyl}-5-methyl-furan-2-carboxylic acid (176) (21 mg, 0.054 mmoles), 2-methyl-benzenesulphonamide (19 mg, 0.108 mmoles) and 4-(N,N-dimethylamino)-pyridine (1 mg) in a mixture of dichloromethane (8 ml) and acetonitrile (2 ml) was treated with 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (11.4 mg, 0.060 mmoles). The mixture was stirred at room temperature for 18 hours under an argon atmosphere. The reaction mixture was concentrated in vacuo and the residue was purified by HPLC to afford compound 177(2.9 mg) as a solid. LC/MS System D; Rt=11.21 mins, m/z (ES+)=541 (M+H for C28H26F2N2O5S).
