Isopropylamine → 2-bromo-N-isopropyl-5-nitropyridin-4-amine

Participants

Reaction Steps

A solution of isopropylamine (17 ml, 34.0 mmol) in THF (14 ml) was added dropwise over 1 h to a mixture of 2,4-dibromo-5-nitropyridine (4.94 g, 17.0 mmol) in THF (85 ml) at room temperature. After 5.5 h, the reaction mixture was diluted with H2O and extracted with EtOAc (3×). The combined organic layers were dried over Na2SO4 and evaporated to give the crude title compound as a yellow solid. (UPLC-MS 6) tR 1.03; ESI-MS 260.0/262.0 [M+H]+.
