(R)-2,3-Dihydrobenzo[1,4]dioxine-2-carbonyl chloride (54 mg, 0.27 mmol) was dissolved in DCM (4 ml). 3-(3-Methoxyphenyl)piperidine HCl (72 mg, 0.26 mmol) and triethylamine (59 mg, 0.58 mmol) were added. After stirring for 1 h, acidic work-up as above gave the crude product, which was purified by flash chromatography using heptane/EtOAc as eluent. The second eluting diastereomer was collected to give 19 mg of A14.
