一般說明

3-Amino-2-methyl-4(3H)quinazolinone is a quinazoline derivative. 2-Methyl-3,1-benzoxazin-4-one undergoes condensation reaction with hydrazine hydrate to yield 3-amino-2-methyl-4(3H)quinazolinone. It undergoes condensation with various substituted aldehydes to afford Schiff′s bases.

應用

3-Amino-2-methyl-4(3H)quinazolinone may be used to synthesize:
  • 2-methyl-3-[3′-aminophthalimido]-4(3H)-quinazolinone
  • 2-alkyl-3-(methylamino)-4(3H)-quinazolinone
  • 3-amino-2-chloromethyl-4(3H)-quinazolinone
