To a solution of spiro[5.5]undec-1-en-3-one (8.9 g) obtained in Step 1 in tetrahydrofuran (360 mL) was added 5% palladium carbon (0.89 g), followed by stirring the reaction mixture at room temperature in an atmosphere of hydrogen under normal pressure for 2 hours. Then, the reaction mixture was filtered through Celite and the filtrate was concentrated to obtain spiro[5.5]undecan-3-one (9.3 g).
