In reaction of 2-aminobenzoxazole with propylene oxide in protic solvents, opening of the heterocycle ring occurs along with alkylation. In the case of 2-aminobenzimidazole, only alkylation occurs under similar conditions. We have studied the compositions of the reaction mixtures and the dynamics of formation of the reaction products by mass spectrometry.
