Reaction Steps

A solution of 1-(2-methoxy-6-methylphenyl)-4-methylpiperazine (D29) (6.2 g, 28 mmol) in concentrated sulfuric acid (50 ml) was treated portionwise with potassium nitrate (3.3 g, 33 mmol) over 5 mins, maintaining the temperature at 25-30° C. The mixture was stirred overnight at room temperature, then added to ice, and basified with 40% sodium hydroxide solution. The mixture was extracted with dichloromethane and the organic phase was dried (Na2SO4) and evaporated under reduced pressure to give crude compound. Purification by chromatography on silica gel eluting with methanol and dichloromethane afforded the title compound (D30) (4.56 g, 61%) MH+=266.
