실험 절차
To a stirred solution of 3,6-dihydro-6-(4-ethoxyphenyl)-3-hydroxymethyl-5-methyl-2H-1,2-oxazine hydrochloride (1.31 g, 4.59 mmol) and triethylamine (1.34 ml, 9.63 mmol) in dichloromethane (50 ml) was added 4-N-acetylsulphanilyl chloride (1.07 g, 4.59 mmol). After 4 h at room temperature, the reaction mixture was washed twice with water and brine. The organic phase was dried over magnesium sulphate, filtered and evaporated to a foam, purified on flash silica eluting with ethylacetate to give 2-(4-acetamidobenzenesulphonyl)-3,6-dihydro-6-(4-ethoxyphenyl)-3-hydroxymethyl-5-methyl-2H-1,2-oxazine as a white foam. 1H NMR (CDCl3)δ 1.39(3H, t), 2.21(3H, s), 3.85(2H, m), 4.00(2H, q), 4.54(1H, m), 5.32(1H, s), 5.70(1H, m), 6.80(2H, d), 7.09(2H, d), 7.54(1H, bs) 7.63(2H, d), 7.85(2H, d).
