実験手順
Benzyl 4-(1,2-dihydroxy-2-methylpropyl)-4-(hydroxymethyl)piperidine-1-carboxylate (from step (iii) above; 340 mg) was dissolved in dichloromethane and p-toluenesulfonyl chloride (190 mg) was added, followed by triethylamine (0.14 mL). This mixture was stirred for 2 h and a second aliquot of triethylamine was added and the mixture was stirred for 12 h. The mixture was concentrated in vacuo. The crude product was purified by chromatography on silica using 50-100% ethyl acetate in iso-hexane as eluant to afford the product (190 mg).
