The protection of the hydroxy group of p-cresol 1 by o-silylation gives derivatives 2 and 3 the methyl group of which can be brominated by NBS. The phase transfer catalysis applied to 4 and 5 is a good way which permits the mild introduction of the allylthio group (6 and 7). Hydroboration applied to silylated compounds 8 and 9 followed by methanolysis and hydrolysis leads to target acids 10 and 11 in a good yield.
