Procedure
After the addition of sodium methoxide add 1.5 grams pigmentary mono-chloro-copper phthalocyanine. Finally raise the temperature to reflux and reflux 8 hours. After reflux, filter, wash with methanol and then water. The pigment is purified in the manner of Example 7 to give 28 grams of pigmentary alpha copper phthalocyanine.
