| titleOfInvention | N-5-protected 2,5-diamino-4,6-dichloropyrimidine and process for producing the same |
| abstract | (57) [Summary] (Modified) [Purpose] N-5-protected 2,5-diamino-of formula I Provided is an improved process for making 4,6-dichloropyrimidine. The N-protected aminomalonic acid ester of formula II is cyclized with guanidine in the presence of an alkali alcoholate to an N-5-protected 4,6-dihydroxy-2,5-diaminopyrimidine of formula III, which is obtained A compound of formula I by chlorination of the compound with phosphorus oxychloride, And compounds of formula I. [Wherein R is an alkoxy group or CF 3 and R 1 is C Meaning 1 to 4 lower alkyl groups] [Effect] The compound of formula I is an intermediate for producing a drug having antiviral properties. |
