Versuchsvorschrift
To a suspension of the compound of Example 17 (768 mg, 2.01 mmol) in ethyl acetate (30 ml) was added ethyl 4-isocyanatobenzoate (769 mg, 4.02 mmol), and the mixture was refluxed for 48 hours. After cooling with ice, the precipitated crystals were collected by filtration, washed with ethyl acetate, and then dried under reduced pressure, thereby obtaining 1.13 g of title compound as colorless powder. Yield 98%.
