실험 절차

Step AU (1). A solution of 3-hydroxybenzaldehyde (67 g, 549 mmol), 2-iodopropane (100 g, 588 mmol) and K2CO3 (130 g, 942 mmol) in 400 mL DMF was stirred for 18 h. To the above solution was added 2-iodopropane (20 g, 117 mmol) and K2CO3 (20 g, 145 mmol) and the mixture was stirred for another 24 h. The reaction mixture was poured into 300 mL water which was extracted with EtOAc (200 mL×3). The combined organic layers were washed with water (100 mL×3), dried over Na2SO4, filtered, and concentrated in vacuo to afford 77 g (85% yield) of 3-isopropoxybenzaldehyde as an oil. 1H NMR (300 MHz, CDCl3) δ 1.29-1.31 (d, 6H) 4.5-4.6 (m, 1H) 7.0-7.1 (m, 1H) 7.3-7.4 (m, 3H).
