Participants

Reaction Steps

To a stirred solution of 4-(biphenyl-4-yloxymethyl)-5-methyl-furan-2-sulphonic acid amide (45) (50 mg, 0.146 mmoles) in N,N-dimethylformamide (4.0 ml) was added diisopropylethylamine (85 μl, 0.480 mmoles) then a solution of 3-methoxypropionic acid (14 μl, 0.146 mmoles) in N,N-dimethylformamide (11.0 ml). O-(7-Azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (61 mg, 0.160 mmoles) in N,N-dimethylformamide (1.0 ml) was added and the solution stirred at room temperature for 16 hours. The reaction mixture was concentrated in-vacuo, and the residue was purified by HPLC to give compound 65 as a white solid (42 mg). LC/MS System A: Rt=3.80 mins, m/z (ES−)=428 ((M−H) for C22H23NO6S).
