25.0 g (0.0899 mol) of tert-butyl-dimethyl-(2-vinyl-5-methoxy-benzyloxy)-silane (15) was dissolved in 100 mL of ethyl acetate and was placed in a 1 L Parr Shaker bottle. 1.93 g (0.0084 mol) of catalyst (PtO2) was added and the solution was placed under 30 PSI of hydrogen for 25 minutes. The reaction mixture was filtered through a pad of celite and concentrated in vacuo to yield crude product. The crude product was chromatographed on a silica gel column with 40% CHCl3 in hexane to afford 24.85 g (99%) of tert-butyl-dimethyl-(2-ethyl-5-methoxy-benzyloxy)-silane (16).
