LaMattina, John L. published the artcileReaction of α-amino ketone hydrochlorides with ortho esters: an oxazole synthesis, Application In Synthesis of 72571-06-3, the publication is Journal of Organic Chemistry (1980), 45(11), 2261-2, database is CAplus.
Reaction of α-amino ketone hydrochlorides with triethyl orthoesters gives 5-monosubstituted and 2,5-disubstituted oxazoles I (R = 4-pyridyl, Ph, p-O2NC6H4, p-BrC6H4; R1 = H, Me, Et). The reaction is most successful when the substituent adjacent to the keto function is electron deficient. Subsequent chem. reactions, however, provide derivatives in which the corresponding electron excessive compounds are available.
