실험 절차

To a solution of 2 (1.83 g, 8.09 mmol) in DMF (30 mL) was added cyanuric chloride (1.50 g, 8.09 mmol) and stirred for 2 h. The reaction was diluted with water (100 mL) and extracted with EtOAc (2×80 mL). The combined organic extracts were washed with water (2×100 mL), brine (120 mL), dried over MgSO4 and concentrated under vacuum to afford 3 (1.67 g, 99%) as a clear yellow oil; 1H-nmr (400 MHz, CDCl3) δ 3.80-3.58 (m, 2H), 3.40 (d, J=12.0 Hz, 2H), 2.16 (s, 2H), 1.43 (s, 9H), 1.25 (t, J=3.0 Hz, 1H).
