実験手順

A suspension of 3-(4-piperidin-1-ylmethyl-phenyl)-9H-dipyrido[2,3-b;4′,3′-d]pyrrol-6-amine (80.9 mg, 0.226 mmol) in DCM (1.8 mL) was treated with isobutyryl chloride (26.3 μL, 0.249 mmol) and DIPEA (118 μL, 0.679 mmol). The reaction mixture was treated with saturated sodium bicarbonate and diluted with 20% MeOH in DCM and water. The layers were separated, the aqueous phase extracted into 20% MeOH in DCM, and the combined organic phase was dried over sodium sulfate and concentrated in vacuo. The resultant residue was dissolved in DCM/methanol, absorbed onto celite, and purified by preparative HPLC (0-30% MeCN/water modified with 0.1% formic acid) to afford an off-white solid (12 mg, 12%). 1H NMR (DMSO-D6, 400 MHz): 12.03 (s, 1H), 10.32 (s, 1H), 8.95 (d, J=2.2 Hz, 1H), 8.90-8.85 (m, 2H), 8.62 (s, 1H), 7.79 (d, J=8.1 Hz, 2H), 7.42 (d, J=8.1 Hz, 2H), 3.48 (s, 2H), 2.79 (dt, J=6.7, 13.5 Hz, 1H), 2.36 (m, 4H), 1.58-1.46 (m, 4H), 1.41 (m, 2H), 1.14 (d, J=6.8 Hz, 6H). LCMS (Method D): RT=7.73 min, M+H+=428.
