After replacement with hydrogen atomosphere, the mixture was catalytically hydrogenated under atmospheric pressure at room temperature. After 3 hours, the mixture was filtered through Celite, the filtrate was distilled off under reduced pressure, and diethyl ether was added. Crystals precipitated were filtered, and 25 mg of Compound I-118 was obtained (yield 42%). mp 145-148° C.
