実験手順
p-Toluenesulfonic acid monohydrate (6.00 mg, 0.0338 mmol) was added to methyl 4-{(1S)-1-[({2,5-dichloro-4-[(3-chlorophenyl)(tetrahydro-2H-pyran-2-yloxy)methyl]-3-thienyl}carbonyl)amino]ethyl}benzoate from Example 8, Step 4 (197 mg, 0.338 mmol) in MeOH (2 mL). After 1.5 h, the reaction mixture was quenched with 5% aq. NaHCO3 and extracted with EtOAc. The combined organics were washed with 5% aq. NaHCO3, water and brine, dried (Na2SO4) and concentrated. The crude product was purified by Combi Flash chromatography system (2-8% EtOAc/toluene in 20 min.) to afford the desired product as a colorless gum.
