실험 절차

Using the same procedure as described in Example 1B, the reaction mixture of the title compound of 53B (0.68 mmol) and 3-benzenesulfonyl-6-isothiocyanato-3-aza-bicyclo[3.1.0]hexane (6.71 mmol, prepared in 1A) was heated to reflux overnight under an atmosphere of dry N2. It was then poured into 10% K2CO3 aqueous solution and extracted with CH2Cl2. The organic layer was washed with brine, dried over MgSO4 and concentrated to afford the crude product. The crude product was chromatographed on silica gel with MeOH—CHCl3—NH4OH (1:99:0.1) as eluents to afford the title compound of 56B as a yellow solid, 0.548 g (0.558 mmol, 82% yield).
