실험 절차

DCC (1.60 g, 7.75 mmol) was added to a solution of 2-iodoacetic acid (1.44 g, 7.74 mmol), 2-[(4-isopropoxy-3-methoxy-phenyl)ethynyl]-5-isopropoxy-4-methoxyphenol (2.6 g, 7.03 mmol)and DMAP (43 mg, 0.35 mmol) in CH2Cl2 (30 mL) and the solution thereby obtained was stirred at 18° C. for 3 h. The resulting suspension was filtered (CH2Cl2 rinse) and the filtrate concentrated under reduced pressure. The residue was suspended in ether (30 mL) at 0° C. with rapid stirring then filtered [rinsing with Et2O (20 mL) pre-cooled at 0° C.] giving the title compound (3.67 g, 97%) as a cream solid mp 127-8° C. IR (KBr disc, cm−1) 2969, 2930, 2833, 1755, 1611, 1575, 1516, 1467, 1416, 1402, 1385, 1365, 1320, 1252, 1236, 1212, 1135, 1108. 1H NMR (300 MHz, CDCl3) δ 7.08 (dd, J=1.8, 8.4 Hz, 1H), 7.04 (d, J=2.1 Hz, 1H), 7.01 (s, 1H), 6.82 (d, J=8.4 Hz, 1H), 6.65 (s, 1H), 4.53 (septet, J=6.0 Hz, 2 Hz), 3.95 (s, 2H), 3.85 (s, 6H), 1.38 (d, J=6.0 Hz, 6H), 1.37 (d, J=6.0 Hz, 6H). 13C NMR+APT (75.5 MHz, CDCl3) δ 167.3 (C), 150.0 (C), 148.4 (C), 148.3 (C), 148.2 (C), 145.1 (C), 125.2 (CH), 115.6 (C), 115.3 (CH), 115.2 (CH), 115.0 (CH), 108.8 (CH), 93.6 (C), 82.7 (C), 72.0 (CH), 71.6 (CH), 56.5 (CH3), 56.3 (CH3), 22.3 (CH3), 22.0 (CH3), −6.2 (CH2).
