Procedure
To a solution of 34.5 g of 1-methyl-2-pyrrolidinone in 150 ml. of CH3CN was added 18.4 g of phosphorous oxychloride at 5°-10° C. The mixture was stirred at room temperature for 1 hour. To the mixture was added 11.9 g of 2,6-diaminoanthraquinone. The resulting mixture was stirred at 60° C. for 10 hours, poured into 1000 ml of ice-water and basified with 5N NaOH. Reddish crystals thus obtained were collected by filtration and washed with water. Recrystallization from methyl cellusolve gave 14.0 g of reddish crystals, mp 267°-269° C.
