| titleOfInvention | Purification of N4-acylcytidine derviatives via their alkali metal or alkaline earth metal salts |
| abstract | A method for producing a high purity N<4>-acylcytidine derivative. The invention provides a compound represented by the formula (1): <EMI ID=1.1 HE=43 WI=61 LX=1057 LY=650 TI=CF> <PC>wherein R1 represents a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, an alkenyl group having 2 to 4 carbon atoms, an alkynyl group having 2 to 4 carbon atoms, a perfluoroalkyl group having 1 to 4 carbon atoms, or a halogen atom; R2 represents a hydrogen atom, an alkoxyl group having 1 to 4 carbon atoms, an alkoxyl group having 1 to 4 carbon atoms with a substituent, or a halogen atom; R3 represents a methyl group or a phenyl group; and M represents a positive ion of an alkali metal or an alkaline earth metal. A method for producing a compound represented by the formula (2): <EMI ID=1.2 HE=43 WI=60 LX=1033 LY=1934 TI=CF> <PC>wherein R1, R2, and R3 are as defined above, comprises using the compound represented by the formula (1), which may be prepared from a compound of formula (2). |
