Versuchsvorschrift

1-n-butyl-3-(β-D-glucopyranosyl)urea (0.50 g) was dissolved in a mixture of water (2 ml) and acetic acid (2 ml), and to the resulting solution was added sodium nitrite (186 mg, 1.5 mol. equivalents). The nitrosation was conducted in the same manner as in Example 1(a). The reaction mixture was treated with Amberlite IR-120 (H+ form) for the removal of sodium cation and then freeze-dried, affording 0.5 g of the titled compound as a glassy substance of pale yellow color. [α]D26 -1.5° (c 1.0, H2O). This substance gave a single spot at Rf 0.51 in a thin layer chromatography on silica gel using chloroform-methanol (4:1 by volume) as eluent.
