Reaction Steps

A mixture of 2-methoxy-3-[4-[2-[N-methyl-N-(2-pyridyl)amino]ethoxyl]-phenyl]propanonitrile (1.15 g), sodium hydroxide solution (10% w/v; 10 mL) and methanol (20 mL) was heated at reflux for 2.5 hrs, cooled and neutralised to pH7 with dilute HCl. The mixture was evaporated in vacuo and the residue redissolved in methanol presaturated with hydrogen chloride gas. The mixture was allowed to stand at room temperature for 7 days, then evaporated. Saturated sodium bicarbonate solution (100 mL) was added and the suspension extracted with ethyl acetate (3×200 mL). The combined ethyl acetate solutions were washed with water (2×500 mL) and brine (500 mL), dried (MgSO4) and evaporated. The resulting gum was chromatographed on silica gel with 1% methanol in dichloromethane to afford the title compound, a gum.
