Route of Synthesis (ROS)
| Conditions | Yield |
| Stage #1: 2-aminoethyl dihydrogen phosphate With potassium tert-butylate In methanol at 20℃; for 0.5h; Cooling with ice; Inert atmosphere; Stage #2: pyridoxal 5′-phosphate With potassium tert-butylate In methanol at 0 – 20℃; for 0.5h; Inert atmosphere; Stage #3: With sodium tetrahydroborate In methanol at 0℃; for 4h; Reflux; Darkness; Inert atmosphere; Experimental Procedure 1 4.2.1. General procedure 1: reductive amination between PLP and selected amines General procedure: To an ice cooled solution of the selected amine (0.1 mmol) in dry CH3OH (3 mL) was added KOtBu (2 equiv) and the mixture was stirred at rt for 30 min (Solution A). Simultaneously, KOt-Bu (2 equiv/mol of PLP) was added to a solution of PLP (1.3 eq.) in CH3OH (3 mL) at 0°C and the mixture was stirred at rt for 30 min(Solution B). Solution A was then added dropwise to solution B at 0°C and the mixturewas refluxed in the dark for 3 h, cooled to 0°C and treated with NaBH4 (1.3 equiv). After stirring at rt for 1 h, the reaction mixture was acidified by dropwise addition of 6 M aq. HCl and the solvent was evaporated to dryness to give a residue, which was purified as indicated below. | 79% |
