Reaktionsschritte

To a solution of the compound of Example 44 (0.511 g, 1.1 mmol) in dry THF (20 mL) was added sodium hydride (60% in mineral oil, 48 mg, 1.2 mmol), and the slurry heated at 40° C. under argon with stirring for 20 minutes. Phenylsulfonylisocyanate (160 μL, 1.2 mmol) was added and the mixture was stirred for 14 hours. The solvent was then removed by rotary evaporation to give the crude product. The solid material was washed twice with 20 mL CH2Cl2, and then twice with 20 mL MeoH: CH2Cl2 (1:1) to give the title compound (274 mg).
