Versuchsvorschrift
Using analogous reagents and reaction conditions as described in Example 30 for the preparation of I-30c above, benzyl 4-(2-methoxypyridin-4-yl)-3-oxo-2,4-diazabicyclo[3.1.0]hexane-2-carboxylate (150.0 mg, 0.442 mmol) was treated with 10.0 mL of 6N HCl to yield the crude product. Purification by column chromatography on silica gel (1.5% methanol in chloroform) afforded 60 mg of the product (67% yield).
