Reaction Steps
In a similar manner to that described in Example 122, a reaction was carried out using methyl 3-[4-(2-t-butoxycarbonylaminoethoxy)phenyl]-2-hydroxypropionate (415 mg), which is obtained in a similar manner to that described in Reference example 39(a), 2-mercaptobenzoxazole (277 mg), tributylphosphine (0.46 ml) instead of triphenylphosphine and 1,1′-(azodicarbonyl)dipiperidine (460 mg) instead of diethylazodicarboxylate and the reaction mixture was treated to afford the desired compound (665 mg) as a colorless oil which contained some impurities.
