Reaction Steps
To a mixture of methyl gentisate (16.8 g, 0.1 mol) and potassium carbonate (15.2 g, 0.11 mol) in 80 ml of DMF, under a nitrogen atmosphere at 80° C., was added chloropropyltrimethylsilane (16.6 g, 0.11 mol) dropwise over 20 minutes. The mixture was heated at 90° C. for 8 hours. It was cooled and poured into 200 ml of water. The mixture was extracted with diisopropyl ether. The organic phase was washed with water, dried over sodium sulphate and then concentrated. After chromatography on silica of the yellow oil obtained (eluent: 90/10 heptane/CH2 Cl2), 3.3 g of a clean fraction of methyl 2-hydroxy-5-(3-trimethylsilanylpropyloxy)benzoate were recovered.
