100% | With dipyridinium dichromate In dichloromethane at 20℃; for 17 h; | A dispersion of (3-methoxy-4-nitrophenyl)methanol (43) (1.4 mmol) and pyridinium dichromate (2.3 mmol) in dry DCM(38 mL) was stirred 17 hours at room temperature and a mixture of celite and silica was added. The dispersion was filtered and washed with DCM (3x10 mL). The solvent of the resulting solution was evaporated under vacuum to give a brown residue (1.3 mmol, quantitative yield). 1H NMR (400 MHz, CDCl3) δ 10.05 (s, 1H), 7.92 (d, J = 8.1 Hz, 1H), 7.60 (d, J = 1.3 Hz, 1H), 7.54 (dd, J = 8.1, 1.5 Hz, 1H), 4.03 (s, 3H). |
79.71% | With manganese(IV) oxide In dichloromethane at 40℃; for 12 h; | 3-Methoxy-4-nitrobenzyl alcohol (4.70g, 25.66mmol) was added to DCM (50mL), and MnO2 (13.39g, 153.96mmol) was added to the mixture and the reaction mixture was warmed to 40°C and stirred for 12 hours. TLC showed the reaction was complete, the reaction mixture was filtered and the filtrate was concentrated to deliver the title compound (yellow solid, 3.90g, yield 79.71percent). 1H NMR (300 MHz, CDCl3): δ 10.0-10.20 (m, 1 H), 7.87 - 8.05 (m, 1 H), 7.47 - 7.72 (m, 2 H), 3.96 - 4.14 (m, 3 H). |
74% | With dipyridinium dichromate In dichloromethane at 20℃; for 2 h; molecular sieve | Step 1 : To a solution of 3-methoxy-4-nitrobenzyl alcohol (5g) in DCM ( 100 mL) was added PDC (1 .5 eq) and molecular sieves (6.0 g). The mixture was stirred at room temperature for 2h and diluted with Et20 (100 mL). The mixture was filtered through a Celite pad and solvent was evaporated. The residue was washed with a small amount MeOH to give off white solid (3.7 g, yield 74percent). |

15% | With hydrogen In methanol | A solution of 3-methoxy-4-nitrobenzyl alcohol (5 g, 27 mmol) in methanol (250 mL) was added to a flask containing 10percent Pd-C (5 molpercent). The mixture was stirred under hydrogen atmosphere for overnight. The reaction mixture was then filtered through a plug of celite and the filtrate was concentrated. The crude product was purified on silica gel column eluting with EtOAc/hexanes to give pure product as a colorless oil (0.5 g, 15percent). |
