Procedure

3-(hydroxymethyl)-7a,8,9,10-tetrahydro-5H-pyrido[3,2-b]pyrrolo[1,2-d][1,4]diazepin-6(7H)-one (100 mg, 0.429 mmol), 4-(piperazin-1-yl)benzonitrile (96 mg, 0.514 mmol), (cyanomethyl)trimethylphosphonium iodide (167 mg, 0.685 mmol) and N,N-diisopropylethylamine (0.374 mL, 2.141 mmol) were suspended in propiononitrile (Volume: 2 mL) and heated in a closed vial at 90° C. for 5 h. The reaction mixture was cooled, diluted with DMSO (2 mL) and purified using preparative HPLC (basic phase, 25-95% ACN). The fractions containing product were concentrated in vacuo and crystallized from water (5 mL). The precipitate was filtered and dried in vacuum to afford 4-(4-((6-oxo-6,7,7a,8,9,10-hexahydro-5H-pyrido[3,2-b]pyrrolo[1,2-d][1,4]diazepin-3-yl)methyl)piperazin-1-yl)benzonitrile (124.2 mg, 0.309 mmol, 72.1% yield) as a light brown solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 1.51-1.65 (m, 1H) 1.72-1.86 (m, 1H) 1.87-1.97 (m, 1H) 2.14 (qd, J=5.81, 4.04 Hz, 1H) 2.40-2.48 (m, 4H) 2.52-2.59 (m, 1H) 2.66 (dd, 1H) 3.30 (br. s., 4H) 3.33-3.40 (m, 2H) 3.45-3.54 (m, 1H) 3.66 (td, J=10.61, 6.82 Hz, 1H) 3.88 (td, J=9.47, 6.06 Hz, 1H) 7.00 (d, J=9.35 Hz, 2H) 7.14 (d, J=2.02 Hz, 1H) 7.57 (d, J=9.09 Hz, 2H) 7.75 (d, J=2.02 Hz, 1H) 9.56 (d, 1H).
