The compound of formula I is obtained, for example, by oxidizing the sulfanyl group of a compound of formula II into sulfonyl group through reaction with an oxidizing agent such as NAIO4 or m-chloroperbenzenecarboxylic acid.
Abstract:
PROBLEM TO BE SOLVED: To obtain a new pyrazolopyrimidine compound and a new pyrazolotriazine compound which have selective affinity with 5HT-6 receptors and are useful for preventing and treating central nerve disorders such as psychoses, manic depressive psychosis, dysmnesia, and Alzheimer's disease. SOLUTION: Compounds of formula I and II (R1 is phenyl; R2 is H, a lower alkyl or the like; R3 is amino, imidazolyl or the like; R4 is H, a hydroxy-lower alkyl or the like; R5 is H, a halogen or the like), and their salts, for example, 3-benzenesulfonyl-5-methyl-2-methylsulfanyl-pyrazolo[1,5-a]pyrimidin-7 -ylamine. The compound of formula I is obtained by reacting a compound of formula III with a compound of the formula: HR3 and then converting the reaction product into its salt. The compound of formula III is preferably dissolved in DMF, and the compound of the formula: HR3 is also dissolved in DMF or an alcohol, followed by reacting the compounds in the solution. The compound of the formula: HR3 is preferably piperazine, NH3, imidazole, or the like. The compound of formula III is preferably obtained from a compound of formula IV as a starting compound.
