YieldReaction ConditionsOperation in experiment
68% In dichloromethane; for 3.16667h; To a solution of 2,2'-(ethylenedioxy)bis(ethylamine) (11.78 mL, 80.5 mmol) in DCM (200 mL) was added BCN-OSu 23 (7.82 g, 26.8 mmol) in DCM (100 mL) dropwise over 3 h. After complete addition the mixture was stirred for 10 min followed by washing with saturated aqueous NH4C1 (3χ200 mL). The organic layer was dried over Na2S04, filtrated and concentrated in vacuo. Flash column chromatography (DCM:MeOH 99: 1-93 :7 + 1% Et3N) gave product 24 (5.95 g, 54.7 mmol, 68%). 1H- NMR (300 MHz, CDC13) δ 5.38 (s, 1H), 4.13 (d, J = 8.1 Hz, 2H), 3.59 (s, 4H), 3.56- 3.50 (m, 4H), 3.35 (q, J = 5.1 Hz, 2H), 2.88 (t, J = 5.1 Hz, 2H), 2.32 (br s, 2H), 2.27- 2.15 (m, 6H), 1.62-1.42 (m, 2H), 1.33 (qn, J = 8.7 Hz, 1H), 0.97-0.85 (m, 2H).13C- NMR (CDC13, 75 MHz) δ 156.4, 98.3, 68.7 (2C), 62.2, 45.5, 40.3, 40.2, 28.6, 20.9, 19.6, 17.3.
