Reaction Steps
In a 5 mL volume glass vessel equipped with a stirrer and a thermometer were placed 1.0 g (3.7 mmol) of 6-methoxy-7-(3-chloropropoxy)quinazolin-4-one prepared by procedures similar to those of Reference Example V-1, 1.62 g (19 mmol) of piperidine, and 10 mL of sec-butyl alcohol. The resulting mixture was stirred at 105° C. for 5 hours. After the reaction was complete, the reaction mixture was analyzed by high performance liquid chromatography (absolute quantitative analysis). There was produced 1.06 g (reaction yield: 90%) of 6-methoxy-7-(3-piperidinopropoxy)quinazolin-4-one.
