Participants

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 (518 mg), which is obtained in a similar manner to that described in Reference example 39(a), 4-methanesulfonylphenol (394 mg), tributylphosphine (0.57 ml) instead of triphenylphosphine and 1,1′-(azodicarbonyl)dipiperidine (578 mg) instead of diethylazodicarboxylate and the reaction mixture was treated to afford the desired compound (441 mg) as a mass of foam.
