N-Benzylacetamide → 3-benzyl-7-chloro-2-methylquinazolin-4(3H)-one

참여 물질

반응 단계

2-Amino-4-chlorobenzoic acid (250 mg, 1 eq.) and N-benzylacetamide (261 mg, 1.2 eq.) were dissolved in phosphorus oxychloride (2 ml). The reaction was placed in the microwave for 10 minutes at 150° C. The reaction was quenched by pouring the mixture into ice. The crude product was extracted into ethyl acetate. The ethyl acetate layer was washed with water, 10% aqueous sodium hydroxide, dried with magnesium sulfate, filtered, and concentrated to yield 3-benzyl-7-chloro-2-methylquinazolin-4 (3H)-one as an orange solid.
