YieldReaction ConditionsOperation in experiment
With hydrogenchloride; hydrogen; sodium acetate;aluminum nickel; In methanol; ethanol; water; EXAMPLE 2 4-Methoxy-7-Phenylpteridine To a solution of 0.5 g. of metallic sodium in 50 ml. of methanol was added 1.9 g. of <strong>[4316-94-3]4-amino-6-chloro-5-nitropyrimidine</strong>. The reaction mixture was refluxed for 90 minutes and then cooled. The precipitated solid was filtered, washed successively with 50 ml. of water, 30 ml. of methanol and 30 ml. of ether to yield 1.6 g. (86%) of 4-amino-6-methoxy-5-nitropyrimidine. A suspension of 4.8 g. of this compound in 200 ml. of methanol was hydrogenated over 0.5 g. of Raney nickel at room temperature and atmospheric pressure until 2 liters of hydrogen was absorbed. The mixture was filtered and the filtrate evaporated to dryness to yield crude 4,5-diamino-6-methoxypyrimidine which was used without further purification. Of the above, 3.95 g. was dissolved in 80 ml. of water containing 4.8 ml. of concentrated HCl. After adding 13.4 g. of sodium acetate, the solution was heated to 50 degrees C. and a solution of 6.35 g. of phenylglyoxal monohydrate in 30 ml. of ethanol was added. Work-up of the precipitate was carried out as in Example 1 to yield 5.6 g. of crude 4-methoxy-7-phenylpteridine. After two recrystallizations from DMSO, 1.9 g. (28%) of the pure compound was obtained; melting point: 205-7 degrees C.
