Versuchsvorschrift
2-tert-Butyl-5-ethoxy-oxazole (16.6 g, 98.1 mmol) was dissolved in freshly distilled ethyl acrylate (11.7 mL, 108 mmol). The solution was heated in a sealed tube to 100° C. for 24 h. Upon cooling, the remaining starting materials were distilled away from the product which was further purified by filtration through a plug of silica-gel (methylene chloride) and concentrated to provide 2-tert-butyl-5-hydroxy-isonicotinic acid ethyl ester (11.2 g, 54%) as a pale yellow oil.
