Reaction Steps
A solution of 5-methyl-7-allyloxycoumarin (IV; 13.8 g) in diethylaniline (60 ml) was refluxed for 5 hours. After cooling, EtOAc (250 ml) was added and the mixture was washed several times with dil. HCl and then with water; the solvent was evaporated from the dried (Na2SO4) organic phase and the residue by crystallization from EtOAc gave 5-methyl-7-hydroxy-8-allylcoumarin (VIII; 4.5 g; m.p. 177° C.). ##STR11##
