Procedure
To a solution of 3-[3,5-dimethyl-1-(4-{2-[({[(4-methylphenyl)sulfonyl]amino}carbonyl)amino]ethyl}phenyl)-1H-pyrazol-4-yl]benzoic acid (step 6, 270 mg, 0.52 mmol) in N,N-dimethylformamide (1 mL) was added ammonium bicarbonate (45 mg, 0.57 mmol), pyridine (0.35 mL) and a solution of di-t-butyldicarbonate (120 mg, 0.57 mmol) in N,N-dimethylformamide (1 mL). The mixture was stirred at room temperature for 1 day. After dilution with water (10 mL), extraction with ethyl acetate (30 mL×3) was followed. The organic layer was dried (Na2SO4) and the solvent was removed under reduced pressure. The crude products was purified by TLC with dichloromethane/methanol (10:1) to afford 46 mg (10%) of the title compound as white solids: MS (ESI) m/z 532 [M+H]+, 530 [M−H]−.
