Preparation process of (6R)-tetrahydrobiopterin hydrochloride |
| abstract |
A preparation process of (6R)-tetrahydrobiopterin hydrochloride is provided, which comprises hydrogenating L-biopterin in the presence of a catalyst of Pt group metal in the basic substrate containing solvent, potassium hydroxide and potassium dihydrogen phosphate to obtain (6R)-tetrahydrobiopterin hydrochloride, wherein the pH value of the basic substrate is controlled by potassium hydroxide and potassium dihydrogen phosphate in the range of about 10 to about 13. |
