실험 절차
A mixture of 8.20 g (72.0 mmol) of N-(2-aminoethyl)-N-methyl-1,2-ethanediamine and 6.80 g (24.0 mmol) of 1-(3,5-diamino-6-bromopyrazinoyl)imidazole in 48 ml of tetrahydrofuran was stirred at ambient temperature for 30 minutes. The solution was evaporated and the residue triturated with ether. There was obtained 5.85 g (17.6 mmol, 73%) of 3,5-diamino-N-[2-[(2-aminoethyl)methylamino]ethyl]-6-bromopyrazinecarboxamide; mp 148°-150° C.
