Reaction Steps

(S)-3-(hydroxymethyl)-6a,7,8,9-tetrahydropyrido[3,2-e]pyrrolo[1,2-a]pyrazin-6(5H)-one (1.500 g, 6.84 mmol), N-methyl-4-(piperazin-1-yl)benzamide (1.500 g, 6.84 mmol), (cyanomethyl)trimethylphosphonium iodide (2.494 g, 10.26 mmol) and N,N-diisopropylethylamine (5.97 ml, 34.2 mmol) were suspended in propiononitrile (Volume: 27.4 ml) and heated in a closed vial at 90° C. The crude reaction was cooled to RT, DMSO (1 ml) was added, and the mixture was purified via HPLC (55-90, basic) to give the product as a white solid.
