Procedure

A solution of 6-methyl-7-hydroxycoumarin (IV) (11.4 g) in diethylaniline (80 ml) was refluxed for 2 h. After cooling the solution was diluted with n-hexane (500 ml) yielding a precipitate, which was collected by filtration, washed several times with n-hexane and crystallized from EtOAc, yielding 6-methyl-7-hydroxy-8-allylcoumarin (VII) (6.3 g; m.p. 161°-2° C.). ##STR12##
