Participants

Reaction Steps

To 29.82 g of 4,5-dihydro-4,4-dimethyl-2-(2-methyl-3-nitrophenyl)oxazole in 500 ml of tetrahydrofuran is added 0.5 g of 10% palladium on barium sulfate. The mixture is exposed to hydrogen gas until the appropriate quantity of hydrogen is taken up, filtered and the solvent evaporated to give 24.7 g of 3-(4,5-dihydro-4,4-dimethyl-2-oxazolyl)-2-methylbenzenamine as a gum which crystallizes on cooling; mp 45° C.
