33.5% | To a solution of <strong>[167300-06-3]4-methyl-3-[(methyloxy)carbonyl]benzoic acid</strong> (100 mg, 0.52 mmol) in toluene (20 mL) was added triethylamine (0.14 ml_, 1.03 mmol) and diphenyl azidophosphate (0.13 mL, 0.62 mmol) were added. The reaction mixture was stirred 5 hours at 90 C. After cooling, ethyl 3-amino-5-chloro-1 -[2'-hydroxy-3'-(methyloxy)-4- biphenylyl]-1 H-pyrrole-2-carboxylate (Intermediate 8; 200 mg, 0.52 mmol) was added and the reaction was stirred 3 days at 50C. Water was added to the reaction and toluene was evaporated in vacuo. After extraction with DCM, drying on sodium sulfate and evaporation, the product was purified by chromatography on silica gel using cyclohexane/EtOAc 90/10 to 80/20 as gradient. The pure fractions were concentrated in vacuo to give the title compound ethyl 5-chloro-1-[2'-hydroxy-3'- (methyloxy)-4-biphenylyl]-3-[({4-methyl-3-[(methyloxy)carbonyl]phenyl}amino)carbonyl]amino}-1 H-pyrrole-2-carboxylate (100 mg, 0.17 mmol, 33.5 % yield) as a white solid.LCMS: (M+H)+=578, Rt= 4.03 min. |

Further HATU (100 mg, 0.26 mmol) was added and the reaction was stirred for a further 1hour. The reaction was then partitioned between 4:1 EtOAC / heptane (30 ml) and water (30 ml)then the organic layer was separated, dried over Na2SO4, filtered and concentrated in vacuo. The residue was purified via flash chromatography using gradients from heptane to EtOAc followed by EtOAc to methanol to yield the title compound as a white powder (285 mg, 44%).LCMS Method 2 - Tr = 1.12 mm (ES+) (M+Ffb) 364.1 |
