Versuchsvorschrift

To 25.8 mmol methyl-5-acetyl-2-hydroxybenzoate, 28.3 mmol 2-propanol and 29.6 mmol triphenylphosphine in 100 ml THF was added 28.3 mmol di-tert-butyl azodicarboxylate, and the mixture was stirred at RT for 90 min. The mixture was then concentrated in vacuo to afford the title compound. MS (m/e): 237.1 (M+H+, 100%)
