How is 1,3-Benzoxazole-6-carbaldehyde (CAS: 865449-97-4) typically synthesized?

1,3-Benzoxazole-6-carbaldehyde is often synthesized via the condensation of benzaldehyde and oxazole, or by the alkylation of 1,3-benzoxazine-6-carbonitrile. The reaction typically involves the use of a base like sodium hydroxide to promote deprotonation and subsequent nucleophilic substitution. The yield is generally good, and the product can be purified by recrystallization.
