実験手順

To a solution of trans-4-((3-(4-((tert-butyl(dimethyl)silyloxy)methyl)-2-chloro-5-methoxyphenylamino)-3-oxopropyl)(methyl)amino)cyclohexyl hydroxy(di-2-thienyl)-acetate (intermediate 41; 0.76 mg, 1.08 mmol) in tetrahydrofuran (19 mL) was added hydrochloric acid 1M (3.25 mL, 3.25 mmol). The mixture was stirred at room temperature for 3 hours. The reaction mixture was neutralized by a saturated solution of sodium bicarbonate and extracted with ethyl acetate. The crude obtained was purified by column chromatography with silica gel, eluting with chloroform/methanol 50/1 to give the title compound as an oil (84%).
