실험 절차

To a solution of KOtBu (6.68 g; 59.5 mmol) in 2-methyl-2-butanol (100 mL) was added dropwise a solution of N-[2-(4-benzyloxy-phenyl)-2-hydroxy-ethyl]-2-chloro-acetamide (17.30 g; 54.1 mmol) in THF (100 mL). The resulting mixture was stirred for 1 hour at RT and then concentrated in vacuo. The residue was dissolved in CH2Cl2 and treated with a 1M aqueous solution of HCl, at 0° C. The layers were separated and the aqueous layer extracted with CH2Cl2. The combined organic layers were dried (Na2SO4), filtered and concentrated in vacuo to afford 6-(4-benzyloxy-phenyl)-morpholin-3-one (14.10 g).
