실험 절차

1-Phenylpiperazine hydrochloride (11.9 mg, 0.060 mmol), (cyanomethyl)trimethylphosphonium iodide (0.025 g, 0.102 mmoles), and (S)-3-(hydroxymethyl)-6a,7,8,9-tetrahydropyrido[3,2-e]pyrrolo[1,2-a]pyrazin-6(5H)-one (0.014 g, 0.063 mmoles) were diluted with propionitrile (0.5 ml) and treated with DIPEA (0.017 ml, 0.100 mmol). The reaction mixture was stirred at 90° C. overnight. The reaction mixture was washed with water (1 mL) and concentrated. The residue was dissolved in DMSO (1 mL) and purified using HPLC (acetonitrile-water, NH4HCO3 buffered). The fractions were concentrated in vacuo, dissolved in dioxane-water (1:1, 2 mL) and lyophilized to yield the title compound as a white solid (5.1 mg, 23%). [M+H] calc'd for C21H25N5O 364; found, 364.
