실험 절차

A solution of 6,7-diethyl-2,3-dip-tolyl-5H-pyrrolo[2,3-b]pyrazine (step 1) (14 mg, 0.039 mmol) in dry DMF (1 ml) under nitrogen was treated with NaH (1.733 mg, 0.043 mmol). The resulting mixture was stirred at RT for 20 minutes and treated with ethyl 7-bromoheptanoate (8.44 μl, 0.043 mmol). After stirring at RT for 3 hours, the mixture was added to water and the pH was adjusted to pH1 using 2M HCl. The aqueous was extracted with EtOAc (×3) and the combined organic extracts were sequentially washed with water (×1) and brine (×1), dried (MgSO4), filtered and concentrated under reduced pressure to afford the title compound (with trace hydrolysis acid product present);
