Method for producing valsartan |
| abstract |
Disclosed is a method for producing valsartan having a valsartan enantiomer content of 0.25% or less and an organic solvent content of 1000 ppm or less, comprising drying crude valsartan having a valsartan enantiomer content of 0.20% or less and an organic solvent content of 3000-25000 ppm inclusive at a temperature of 50-65ºC. The crude valsartan is obtained by, for example, drying a wet substance of valsartan having a valsartan enantiomer content of 0.20% or less and an organic solvent content of 150000-600000 ppm inclusive obtained by depositing synthetically obtained valsartan in an organic solvent and separating the deposited crystals of valsartan at a temperature lower than 50ºC. |
