    • 2, and then it was poured into 80 mL water. The colloidal solution thus formed was destroyed by sodium sulfate. The precipitated solid was filtered and crystallized from the corresponding solvent. Recrystallization was carried out as follows. The substance was dissolved in a minimum volume of solvent at 30°C (at higher temperature decomposition is high) and left at 0°C under argon for 10-12 h.

    • Typical procedure: To a solution of N-benzyl-3-cyanopyridinium chloride 1 and 2 mmol of triethylamine in DMSO 3 mL was added a solution of 6-aminouracil 6 in DMSO 5 mL. The reaction mixture was maintained under argon at 4°C for 12 h, and then poured into 50 mL of water. The precipitated solid was collected by filtration and recrystallized from acetonitrile.
