Participants

Reaction Steps

To a solution of vanillic acid (2.0 g, 11.89 mmol) in N,N-dimethylformamide (50 ml), imidazole (4.04 g, 59.45 mmol) and tert-butyldimethylchlorosilane (4.48 g, 29.72 mmol) were added. The reaction was stirred at room temperature for 24 hours. he mixture was poured in water (70 ml) solution and extracted with diethyl ether (3×70 ml) The organic layers were dried over sodium sulfate and concentrated under reduced pressure. The residue was purified by flash chromatography (Biotage System, column FLASH 40+M™ KP-C18 HS, eluent: gradient acetonitrile/water 65/35 (600 ml), to acetonitrile/water 80/20 during 1200 ml). The product (0.70 g) was obtained.
