A solution of 2-methylallyl 2,3-difluoro-6-(2-methylallyloxy)benzoate (733) (1.53 g, 5.42 mmol) in NMP (3.5 mL) was heated in the microwave at 200° C. for 6 h. The solvent was removed in vacuo to provide 2-methylallyl 2,3-difluoro-6-hydroxy-5-(2-methylallyl)benzoate (734) (1.53 g) which was directly used in the next step reaction without further purification.
