Reaction Steps

3 g (0.017 moles) of 2-cyano-3-methoxy-4-nitropyridine obtained in Example a) and a sodium methoxide solution prepared from 0.77 g (0.033 moles) of sodium and 65 ml of methanol are stirred at ambient temperature for 4 hours. There is added 100 ml of water, the methanol is eliminated and the aqueous phase is extracted with dichloromethane. The organic phase is washed with water, dried, concentrated and the residue chromatographed (ethyl acetate/heptane, 1:1) to obtain 1.96 g (72% yield) of a white solid (MP=133° C.).
