Procedure

A mixture of 34 parts of 6-quinolinemethanol, 70 parts of manganese(IV)oxide and 300 parts of trichloromethane was stirred for 24 hours at room temperature. The reaction mixture was filtered over diatomaceous earth and the filtrate was evaporated, yielding 27.7 parts (82.7%) of 6-quinolinecarboxaldehyde; mp. 72° C. (interm. 16).
