Reaction Steps

159 mg of the compound [2-2] was dissolved in a mixed solvent of 4 mL of tetrahydrofuran and 2 mL of methanol, then 48 mg of 10% palladium carbon catalyst was added thereto, and the mixture was further stirred for 2 hours under hydrogen atmosphere. Thereto, 95 mg of 10% palladium carbon catalyst was further added and stirred for 3.5 hours under hydrogen atmosphere. The insolubles were filtered through celite and the filtrate was concentrated under reduced pressure, to obtain tert-butyl{(1S)-1-[4-(N-methylglycyl)phenyl]ethyl}carbamate [2-3] (hereinafter, referred to as the compound [2-3]) as crude and purified products. The compound [2-3] was used in the subsequent reaction without further purification.
