Kulyk-Sindler, Marija published the artcileFormylation of 2,5-unsubstituted oxazoles: preparation and characterization of 2- and 5-formyl-4-methyloxazoles, SDS of cas: 20662-83-3, the publication is Heterocycles (1994), 38(8), 1791-6, database is CAplus.

Vilsmeier formylation of 4-methyloxazole gave a mixture of 4-methyl-5-oxazolecarboxaldehyde (2) and 4-methyl-2-oxazolecarboxaldehyde (3) in a 1:1 ratio. Both aldehydes were prepared unambiguously: aldehyde 2 by oxidation of 5-hydroxymethyl-4-methyloxazole and reduction of the chloride of 4-methyl-5-oxazolecarboxylic acid and aldehyde 3 by BuLi/DMF procedure. Aldehyde 2 sublimes in a refrigerator while aldehyde 3 forms hydrate, 5-dihydroxymethyl-4-methyloxazole.
