With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.147-85-3,H-Pro-OH,as a common compound, the synthetic route is as follows.
Equimolar amounts of mandelic acid, or (R)-(-)-mandelic acid or (S)-(+)-mandelic acid or L-proline and potassium hydroxide (scale 0.1 mol) were dissolved in distilled water (100 mL). After clarity of solution equimolar amount of quaternary ammonium chloride in distilled water (80 mL) was added. The mixture was heated at 60 C for 5 h. The water was removed under reduced pressure (70 C, 30¡Á102 Pa). Anhydrous methanol was added and the mixture was allowed to stand overnight at room temperature. The crystalline potassium chloride was removed by filtration and methanol by distillation. The obtained residue was dried overnight in vacuum at 80 C.
147-85-3 H-Pro-OH 145742, acatalyst-ligand compound, is more and more widely used in various.
