Route of Synthesis (ROS)
| Conditions | Yield |
| Stage #1: biopterin With platinum(IV) oxide; hydrogen; tetraethylammonium hydroxide In water at 20℃; under 15001.5 Torr; for 24h; pH=12; Stage #2: With hydrogenchloride In water Reagent/catalyst; Experimental Procedure 7-8 Example 8 Synthesis of sapropterin hydrochloride 2 DL-5 (20 g, 0.084 mol), water (200 mL) was added to the reaction vessel.Add 25% aqueous solution of tetraethylammonium hydroxide,The pH was adjusted to 12 and DL-5 was substantially completely dissolved.The mixture was transferred to a 2 L hydrogenation reactor, and platinum dioxide (2.0 g) was added thereto. After replacing three times with hydrogen, the mixture was hydrogenated to 2 MPa, and reacted at room temperature for 24 hours. The reaction was monitored by HPLC until the reaction was completed.The catalyst was removed by filtration, the filtrate was collected, concentrated hydrochloric acid was added, the mixture was adjusted to pH 1 and the solvent was evaporated to dryness, and ethyl alcohol (2000 mL) was added, and the mixture was stirred for 1 hour, and the filtrate was collected and dried to give a brown-brown oil (22 g).Add 66 mL of concentrated HCl (10N), heat to complete dissolution, add ethanol (220 mL), precipitate solids, filter, rinse with ethanol, collect solids, and dry.White crystals of sapropterin hydrochloride 17.9g,The yield was 88.3% and the ee value was 99%.The HPLC diagram of the final product of sapropterin hydrochloride is shown in Figure 2 of the specification. | 88.3% |
