Hydrochloric Acid → 1-(2,3-Dihydrobenzo[1,4]dioxin-2-ylmethyl)-3-o-tolylpiperidine

Participants

Reaction Steps

A mixture of 2-bromomethyl-2,3-dihydrobenzo[1,4]dioxine (35 mg, 0.15 mmol), 3-(2-methylphenyl)piperidine.HCl (35 mg, 0.16 mmol) and triethylamine (38 mg, 0.38 mmol) in acetonitrile (2 mL) was heated in a microwave reactor at 140-150° C. for 12.5 h. The mixture was absorbed on silica and purified by flash chromatography using a gradient of heptane and EtOAc as eluent to give 29 mg of the title compound.
