実験手順

To a solution of sodium metal (0.6 g.) in absolute alcohol (20 ml.) was added [2,6-diamino-5-(p-chlorophenyl)-4-pyrimidinyl] methyl ketone (2.0 g.) and N-methyl hydroxylamine hydrochloride (1.2 g.), and the mixture was refluxed together for 5 hours. After removal of ethanol, the residue was filtered and recrystallized from ethanol-chloroform to give α-methyl-α-[2,6-diamino-5-(p-chlorophenyl)-4-pyrimidinyl]-N-methylnitrone as a white solid, m.p. 306°-309° (decomposition).
