162 mg of 1-acetyl-7-(2-(1,4-dioxa-8-azaspiro[4.5]decan-8-yl)ethyl)-6-methoxy-1,2,3,4-tetrahydroquinoline was dissolved in 6 ml of 2 N hydrochloric acid-tetrahydrofuran (1:1), and the reaction solution was then stirred at 70° C. for 10 hours. The reaction solution was cooled to a room temperature, and a saturated sodium bicarbonate aqueous solution was added to the reaction solution, followed by extraction with methylene chloride. The extract was dried over magnesium sulfate and then concentrated under a reduced pressure, so as to obtain 127 mg of 1-(2-(1-acetyl-6-methoxy-1,2,3,4-tetrahydroquinolin-7-yl)ethyl)piperidin-4-one. This compound was used in the following reaction without further purification.
