Yield:103853-10-7 98%

Reaction Conditions:

with palladium 10% on activated carbon;hydrogen in methanol; for 1 h;

Steps:

3-(2,3-Dimethoxyphenyl)propan-1-ol (14).

To a solution of 13 (500 mg, 2.3 mmol) in MeOH (10 mL) was added in one portion Pd/C 10% (50 mg, 0.25 mmol). The reaction mixture was stirred for 1 h under hydrogen atmosphere at atmospheric pressure, filtered over celite and evaporated to dryness. The crude product 14 (colorless oil) was pure enough to be used in the next step. (497 mg, 2.5 mmol, 98 %, RF = 0.64, EtOAc/petroleum ether, 8:2). 1H-NMR (300 MHz, CDCl3): δ (ppm) = 1.81 (2H, qui, J = 6.7 Hz, -CH2-), 2.21 (1H, s, -OH), 2.71 (2H, t, J = 7.3 Hz, CH2-Ph), 3.55 (2H, t, J = 6.1 Hz, CH2-OH), 3.80 (3H, s, OMe), 3.83 (3H, s, OMe), 6.75 (2H, d, J = 8.1 Hz, aromatic H-4 and H-6), 6.97 (1H, dd, J = 7.5 Hz, 8.4 Hz, aromatic H-5). 13C-NMR (75.5 MHz, CDCl3): δ (ppm) = 25.7, 33.5, 55.7, 60.8, 61.6, 110.3, 122.1, 124.2, 135.4, 147.1, 152.6. HRMS (EI+) calculated m/z for C11H 16O3Na [M+Na]+ 219.099, found 219.100.
