Participants

Reaction Steps

Briefly, 2-amino-4-nitrobenzoic acid was acylated with propionyl chloride in triethylamine (TEA) and tetrahydrofuran (THF). The acylated compound was refluxed with 2-ethoxyaniline in phosphorus oxychloride (POCl3) and toluene to produce 2-ethyl-7-nitro-3-(2-ethoxyphenyl)quinazolin-4(3H)-one. The 2-ethyl-7-nitro-3-(2-ethoxyphenyl)quinazolin-4(3H)-one was brominated with N-bromosuccinimide (NBS) in carbon tetrachloride, the product of which was subsequently reacted with N-methylhomopiperazine in THF. The product of this reaction was subjected to hydrogenation conditions using catalytic amounts of Pd/carbon (10% Pd) to afford Compound 10.
