Reaction Steps

To a warm and stirred suspension of 4 g (0.02 mole) finely powdered phenothiazine and 4 g (0.024 mole) ethyl-p-aminobenzoate in 200 ml methanol was added a solution of 10 g of iodine in 150 ml methanol. After stirring at room temperature for 2 hours, the dark precipitate was filtered, washed repeatedly with methanol, and dissoved in 100 ml chloroform and 10 ml triethylamine. The chloroform solution was shaken with water and separated. Purification through alumina and recrystallisation from ether gave purple leaflets. Yield 5.5 g (76%).
