반응 단계
A mixture of N-Boc-N-methyl hydroxylamine (132 mg, 0.898 mmol), 2-(2-chloroethoxy) ethanol (168 mg, 1.35 mmol), K2CO3 (372 mg, 2.69 mmol) and LiBr (2 mg, 0.018 mmol) in DMF (3 mL) was heated at 100° C. and stirred for 16 h. The resulting mixture was cooled down to room temperature and filtered. The filtrate was concentrated and the residue was purified by silica gel flash column chromatography using 50% EtOAc/hexanes as eluent to afford the desired product as colorless oil (152 mg, 0.647 mmol, 72%). 1H NMR (CDCl3, 400 MHz): 8 (ppm) 1.45 (s, 9H), 2.68 (br s, 1H), 3.08 (s, 3H), 3.57-3.60 (m, 2H), 3.66-3.72 (m, 4H), 3.96-3.99 (m, 2H).
