실험 절차
The solution of 2.0 g of benzyl 4-(4-methoxycarbonylphenyl)-3-[4-(3-methoxypropyl)-3-oxo-3,4-dihydro-2H-benzo[1,4]oxazin-6-ylmethoxy]piperidine-1-carboxylate (Example 235d) in 16 ml of tetrahydrofuran is admixed with 52.1 ml of 9-BBN and stirred at reflux over 24 hours. The reaction mixture is cooled to room temperature, admixed with 1.58 ml of ethanolamine and concentrated by evaporation. The residue is stirred in 50 ml of ethyl acetate-hexane (1:1) over 1 hour and clarified by filtration, and the filtrate is concentrated by evaporation. The title compound is obtained as a slightly yellowish oil from the residue by means of flash chromatography (SiO2 60F). Rf=0.20 (3:1 EtOAc-heptane); Rt=4.74.
