반응 단계
30 g of 2,4-dichloro-3-methylbenzoic acid are initially introduced into 83 ml of concentrated H2SO4. 16.7 g of KNO3 are added in portions, while cooling with ice. The mixture is subsequently warmed at 50° for a further 2 hours and then poured onto ice. The nitro compound is isolated and recrystallized from toluene. Melting point: 152°-4°, yield: 24 g.
