실험 절차

A solution of compound 1 (136 mg, 0.5 mmol), PPh3 (262 mg, 1.0 mmol, 2.0 eq), and CCl4 (2.5 mL) was refluxed overnight. The resulting mixture was then diluted with water and extracted three times with CH2Cl2. The organic phases were combined, dried with Na2SO4, concentrated, and purified by column chromatography using 5:95:EtOAc:Hexane to give a white solid (74 mg, 51%): mp 106–107° C. (dec). 1HNMR (CDCl3, δ TMS): 0.93 (t, 3H), 1.37 (t, 3H), 1.91 (m, 2H), 2.34 (m, 2H), 2.76 (m, 2H), 2.87 (q, 2H), 3.46 (dm, 2H), 3.99 (m, 2H), 7.04–7.38 (m, 3H, Ar—H), 7.55 (br, 1H, NH). MS−: m/z 326 (MCl−), 290 ([M−H]−). Anal. (C17H22NOCl): C, H, N.
