2,2-Dimethyl-3-phenyl-2H-azirene → 4-(2,2-Dimethyl-4-phenyl-2,5-dihydro-1,3-oxazol-5-yl)-N,N,3,5-tetramethylaniline

Participants

Reaction Steps

2.25 g of 2,2-dimethyl-3-phenyl-2H-azirine and 2 g of 2,6-dimethyl-4-(dimethylamino)benzaldehyde were exposed to light for 3 hours in 350 ml of 1,4-dioxane (with the light source described in Example 2). After purification as described in Example 11 and crystallization from n-pentane, there was obtained 5-[4-(dimethylamino)-2,6-xylyl]-2,2-dimethyl-4-phenyl-3-oxazoline which melted at 105° C. after drying for 4 hours at 60° C. and 13 Torr.
