HCID 2712836-Chloroquinoline-2-carbaldehyde

Conditions

Temperature: 80 °C

Procedure

A suspension of 6-chloro-2-methyl-quinoline (355 mg) and SeO2 (233 mg) in 1,4-dioxane (3 mL) was heated at 80° C. for 16 h. The resulting black mixture was filtered through diatomaceous earth. Concentration of the filtrate gave the title compound as a yellow powder (324 mg).

Workup

filtrationThe resulting black mixture was filtered through diatomaceous earth
