Participants

Reaction Steps

Compound O (0.150 g, 0.578 mmol) was dissolved in toluene (15 ml) and mixed successively with triethylamine (0.12 ml, 0.867 mmol) and 4-tert-butylphenyl isocyanate (0.102 ml, 0.578 mmol). The reaction mixture was heated to boiling point and boiled under reflux for 3 h. After cooling 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:EtOAc 1:1), the desired product was obtained in a yield of 52% (0.120 g).
