Vorschrift

The title product of Example 3 (0.30 g, 1.4 mmol) and 0.06 g (1.1 mmol) of ammonium chloride (NH4Cl) were refluxed in 13 mL of methanol (MeOH) under a nitrogen atmosphere for 19 h. After cooling the reaction to room temperature, it was filtered, stripped of all solvent under reduced pressure, and partitioned between 15 mL of water and 7 mL of CH2Cl2. The organic and aqueous phases were separated and the aqueous phase was washed with a 25 mL portion of EtOAc before it was lyophilized to provide 0.24 g (92%) of the white solid title material.
