Versuchsvorschrift

Chloro-chromic pyridine (161.6 g, 0.75 mole) and 450 ml dichloromethane were added to a flask. With stirring, 150 ml dichloromethane solution of 13-methyl-1-tetradecanol (114 g, 0.50 mole) was slowly added to the flask and stirring continued for 1.5 hours at room temperature. Let the mixture stand and separate into two phases. Decant upper phase and wash the remainder with 100 ml diethyl ether. Combine all liquid and wash sequentially with saturated NaCl, 10% HCl, and saturated NaCl solution with 5% NaHCO3. Desiccate with anhydrous CaCl2 and remove solvent by evaporation to yield 13-methyl-tetradecanaldehyde (57.6 g, yield rate 51%).
