Participants

Reaction Steps

Compound K (0.130 g, 0.451 mmol) was dissolved in toluene (15 ml) and triethylamine (0.12 ml, 0.867 mmol) and 4-tert-butylphenyl isocyanate (0.08 ml, 0.451 mmol) were successively added. The reaction mixture was heated to boiling point and boiled under reflux for 3 h. After cooling of the reaction mixture to RT, the mixture was stirred for 36 h. The reaction mixture was extracted with EtOAc (3×20 ml). The combined organic phases were washed with sat. Na2HCO3 solution (10 ml), dried over Na2SO4 and concentrated to dryness under vacuum. After purification of the residue by column chromatography (hexane:EtOAc1:1), the product was obtained in a yield of 83% (0.160 g).
