Participants

Reaction Steps

4 g of 2,2-dimethyl-3-phenyl-2H-azirine and 5 g of 4-diethylaminobenzaldehyde were exposed to light in 350 ml of benzene at 230° C. for 4 hours under an atmosphere of argon with a mercury high-pressure lamp of 150 watt in a water-cooled ring-mantle vessel through a 3 mm thick filter of Pyrex glass. After removing the solvent in a water-jet vacuum, the residue was crystallized from n-hexane/acetone and then a second time from n-pentane/acetone. The crystalline product was then dried at 60° C. in the water-jet vacuum, and there were obtained 3,4 g of 5-[p-(diethylamino)-phenyl]-2,2-dimethyl-4-phenyl-3-oxazoline having a melting point of 104°-105° C.
