Reaction Steps

745 mg (1.48 mmol) of methyl (R)-2-[(t-butoxycarbonyl)amino]-4-[4-(5H-dibenzo[a,d] [7]annulen-5-ylidene)-1-piperidinyl]-4-oxobutanoate was dissolved in 70 ml of ethanol. 1.49 g of palladium carbon (10% w/v) was added to the obtained solution, and they were stirred at room temperature in hydrogen gas atmosphere under 4.4 atm. for 3.5 hours. The catalyst was filtered out, and the filtrate was concentrated under reduced pressure. The intended product was obtained from the resultant residue in the same manner as that in steps 3 and 4 in Referential Example 50.
