実験手順
To a solution of 7 (0.48 g, 2.00 mmol) in 15 ml of methanol, methyl isocyanate (0.13 g, 2.20 mmol) was added slowly. The solution was stirred at 0° for 1 h, during which period, white crystals precipitated out. The product was collected by filtration, washed with cooled methanol, and dried, to give 0.54 g (90%). The compound softened at 114° and effervesced at 120°; TLC: Rf 0.38. Anal. (C12H18N4O5) C, H, N.
