Procedure

5-phenyl-2-furoic acid (36) (18 mg, 0.15 mmol) was coupled to aniline (43) (30 mg, 0.15 mmol) using Method B, except that DIPEA (40 mg, 0.31 mmol) and DMF (2 mL) were used and the reaction was stirred at ambient temperature for 2.5 hours, then at 40° C. for 24 hours. Further TBTU (1 eq) and acid (1 eq) were added and the reaction heated at 60° C. for a further 6 hours to give the crude title compound after work-up. The residue was purified using column chromatography eluting with 20% EtOAc in heptane to give the title compound. Yield: 18 mg, 32%; LC-MS tr 1.55 min; HPLC Purity: 83%; MS (ES+) m/z 366 (M+H)
