Versuchsvorschrift

To a solution of 4-chloroquinazoline-6-yl-methanol (3.5 g, 0.018 mol) in dry CH2Cl2 (100 mL) was added Dess-Martin periodinane (8.4 g, 0.019 mol) and stirred at RT for 30 min. The reaction mixture was washed with 10% aqueous NaHCO3 (75 mL), water, brine and dried. The solvent was removed under vacuum to give 4-chloroquinazoline-6-carboxaldehyde (3 g, 88%) as pale yellow solid.
