Reaction Steps

A mixture of 4-chloro-2-methyl-quinolin-8-ol (0.10 g, 0.51 mmol) and hydrazine monohydrate (0.75 mL, 15 mmol) in dioxane (10 mL) was heated to reflux for 4 d. The solvent was removed in vacuo and the residue was purified by flash chromatography on silica gel (elution with DCM/methanol/conc. aqueous NH3 5:1:0.033) to give the title compound. MS (m/z): 190.1 [M+H+].
