Reaction Steps

Huperzine A 10 mg, and 37% aqueous solution of formaldehyde were refluxed for 1 hour in 2 mL of isopropanol; the solvent was stripped in vacuo; THF (dry, 5 mL) and NaBH(OOCCH3)3 0.15 g were added, the reaction mixture was allowed to stir for 4 hours; and then filtered to remove solid substances. The filtrate was purified after concentrating on prep TLC (chloroform:methanol=9:1) to yield 6 mg of pure title compound. MS: 257 (M+1).
