| titleOfInvention | NEW PROCEDURE FOR THE PREPARATION OF PYRAZOLOPYRIMIDINONES |
| abstract | REFERS TO A PROCEDURE FOR THE PREPARATION OF A COMPOUND OF FORMULA I WHERE A IS CH, N; R1 IS H, ALKYL, HET, ALKYL-HET, ARYL, ARALKYL WITH ONE OR MORE SUBSTITUTES HALO, CYANE, NITRO, OR5, C (O) R6, C (O) OR7, C (O) NR8R9, NR10aR10b, SO2NR11aR11b, AMONG OTHERS; R2 AND R4 ARE ALKYL; R3 IS ALKYL WITH OR; HET IS A HETEROCYCLE GROUP OF 4-12 MEMBERS WITH HETEROATOMOS; R5-R9 AND R11a AND R11b ARE H, ALKYL; R10a AND R10b ARE H, ALKYL AND TOGETHER WITH N FORM AZETHYDINYL, PYRROLIDINYL, PIPERIDINYL. THE PROCEDURE INCLUDES THE DEHYDROGENATION OF A COMPOUND OF FORMULA II IN THE PRESENCE OF A DEHYDROGENATION AGENT SUCH AS PALADIUM ON CARBON (5% OR 10% Pd / C), IN THE PRESENCE OF A HYDROGEN ACCEPTOR SUCH AS CYCLOHEXENE / ACIDIC ACID. OR AN ACID, A QUINONE WITH A HIGH OXIDATION POTENTIAL, OR, MnO2, TRIPHENYLMETHANOL IN TRIFLUOROACETIC ACID. THE REACTION IS CARRIED OUT BETWEEN 125 ° C TO 250 ° C AT A PRESSURE OF 13.8 AND 68.9 kPa AND / OR AN INERT ATMOSPHERE. IT ALSO REFERS TO THE PROCEDURE FOR THE PREPARATION OF DERIVATIVES OF 4-ALKYLPIPERAZINYLSULFONYLPHENYL- AND 4-ALKYLPIPERAZINYL-SULFONYL-PYRIDINYL-DIHYDROPIRAZOLE [4,3-d] PYRIMIDINE-7-ONA 5-PYRIMIDINE-7-ONA 2-SILICA-2-EYRIMIDINE-7-ONA - (4-METHYLPIPERAZIN-1-ILSULFONIL) PHENYL] -1-METHYL-3-n-PROPYL-1,6-DIHYDRO-7H-PYRAZOLO [4.3] PYRIMIDIN-7-ONA |
