Participants

Reaction Steps

To a solution of the compound obtained in Example 32 (1.37 g, 2.40 mmol) in THF (3 ml) is added pyridine (0.5 ml) and ethyl isocyanate (0.38 ml, 4.8 mmol). Then the mixture is stirred at room temperature overnight. The reaction mixture is concentrated under reduced pressure to give the residue, which triturated with isopropyl ether to afford a crystalline solid, which is recrystallized from chloroform-isopropyl ether to afford pale yellow crystals (1.20 g, 78%).
