YieldReaction ConditionsOperation in experiment
With thionyl chloride; N,N-dimethyl-formamide; for 16h;Reflux; a) Method for synthesising P-1 a:; delta-amino^-chloro-isonicotinic acid (4 g, 23.18 mmol) is taken up in the form of the amide (50 ml.) and stirred for 12 h at 140 0C. The reaction mixture is cooled to RT and mixed with water. The precipitate formed is filtered off, washed with water and then dried at 60 0C for 24h in the vacuum drying cupboard.The intermediate product obtained, 6-chloro-3/-/-pyrido[3,4-c/]pyrimidin-4-one (745 mg, 4.1 mmol), is suspended in thionyl chloride (10 ml_), mixed with one drop of DMF and refluxed for 16 h. The excess thionyl chloride is distilled off. The residue is taken up in DCM, washed 1x with semisaturated NaHCC>;3 solution and saturated NaCI solution, dried on Na2SC>;4 and concentrated to dryness by rotary evaporation. The crude product P-1a is further used directly.
With thionyl chloride; N,N-dimethyl-formamide; for 2h;Reflux; Step 2: containing 20 ml sulfoxide chloride, 1.81 g of 6-chloro-pyrrolo [3,4-d] pyrimidin -4 (3H) - one (10 mmol) and dimethylformamide (catalytic amount ) was heated to reflux for 2 hours, the solvent evaporated the crude product was directly used in the next step without any further purification.
