실험 절차

Sodium hydride (91 mg, 2.37 mmol) was added to a solution of 8-methoxy-2-methyl-3H-quinazolin-4-one (300 mg, 1.58 mmol) in DMF (30 mL). The reaction mixture was stirred at 80° C. for 0.75 h and cooled to room temperature, then a solution of 4-(3-iodo-propyl)-piperidine-1-carboxylic acid tert-butyl ester (837 mg, 2.37 mmol) in DMF (1 mL) was added. The reaction mixture was heated at 85° C. for 17 h and diluted with EtOAc. The organic solution was washed with water and sat'd aq NaCl, dried and concentrated. Purification on SiO2-gel chromatography (50% EtOAc/hexanes) provided the desired product as a yellow oil. API-MS: 416 (M+1).
