Reaction Steps
Dissolve sodium metal (0.345 g) in absolute EtOH (25 mL), add diethyloxalate (10 mL) and then add 3-methyl-4-nitrobenzonitrile (1a, m=0, 1.6 g, Aldrich) as an EtOH solution (25 mL). Stir reaction mixture at rt for 16 h, neutralize the reaction by addition of 5N HCl (3 mL) and remove the EtOH under reduced pressure. Partition the residue between CH2Cl2 (100 mL) and H2O (50 mL). Wash the organic layer successively with H2O (50 mL) and brine (50 mL), dry (MgSO4) and concentrate to give a crude oil. Purify the oil by chromatography on SiO2 (cyclohexane-EtOAc, 70-30 v/v) to give after drying (40° C., house vacuum), the title compound (1.2 g) as yellow crystals.
