실험 절차

7-[5-(Cyclopropylmethoxy)-1,3-benzodioxol-4-yl]-2-methyl-N-piperidin-4-yl-1H-pyrrolo[3,2-b]pyridine-3-carboxamide hydrochloride from example D.f1 (485 mg; 1.0 mmol) and DBU (2.5 mmol) is dissolved in dry dichloromethane (5 mL). Acetyl chloride (1.1 mmol) is syringed into the reaction mixture at ice bath temperature. After addition the mixture is stirring at ambient temperature over night. Methanol (1 mL) is added and stirring is continued for two hours. The volatiles are evaporated. The residue is purified by reversed phase preparative HPLC. The collected product fraction is freeze-dried to yield the title compound as colorless solid.
