Triethylamine → Tert-butyl-dimethyl-(3-piperidylmethoxy)silane

Participants

Reaction Steps

To a solution of piperidin-3-ylmethanol (2.10 g, 0.018 mol) in CH2Cl2 (20 mL) is added triethylamine (5.53 g, 0.0547 mol) followed by t-butyldimethylchlorosilane (4.127 g, 0.0275 mol) and the reaction mixture is stirred at room temperature. After 24 hours, the reaction mixture is washed with water, saturated solution of NaHCO3, and brine. The combined organic layers are dried over sodium sulfate, filtered, and concentrated under reduced pressure. The resulting residue is purified by flash chromatography (silica gel) over a gradient using 0-10% MeOH in dichloromethane to afford the title compound (2.50 g, 60%). Mass spectrum (m/z): 231.2 (M+1).
