The green suspension is slowly heated to 120°C under nitrogen. After 1.5 hours TLC (CH2CI2) analysis showes that all starting material has been consumed. The reaction mixture is cooled to room temperature and filtered. The residue is suspended in 1000 ml of water : ethyl acetate 1 :1 , then 400 ml of NaOH (2N) are added (pH = 10). To the thick green-yellow mixture are added 250 ml of ethyl acetate, then the mixture is stirred for 30 minutes. After filtration (slow) the filtrate is stored during the weekend and shows after that time a nice phase separation. The phases are separated and the water phase is extracted 3 times with 250 ml of ethyl acetate each. The organic phase is washed with 250 ml of a puffer solution of pH 7 and 250 ml of brine, dried over Na2S04, filtered and evaporated to yield 51.7 g (88 %) of yellow crystals of 3,3'-diamino-2,2'- bipyridine.
