Reaction Steps

A mixture of 2-bromomethyl-2,3-dihydrobenzo[1,4]dioxine (340 mg, 0.48 mmol), 3-(3-fluorophenyl)piperidine (323 mg, 2.50 mmol) and triethylamine (455 mg, 4.50 mmol) in acetonitrile (3 mL) was heated in a microwave reactor at 140° C. for 60 min. The mixture was absorbed on silica and purified by flash chromatography using a gradient of heptane and EtOAc as eluent to give 213 mg of the title compound.
