1,1'-Carbonyldiimidazole → Ethyl 3-[4-[2-(4'-methoxymethoxy-3',5'-dimethylbiphenyl-4-carbonylamino)ethoxy]phenyl]-2-phenoxypropionate

Participants

Reaction Steps

In a similar manner to that described in Example 5, a reaction was carried out using ethyl 3-[4-(2-aminoethoxy)phenyl]-2-phenoxypropionate (2.07 g), which is the product of Reference example 4, 4′-methoxymethoxy-3′,5′-dimethylbiphenyl-4-carboxylic acid (1.50 g), which is the product of reference example 17(b), and carbonyldiimidazole (1.10 g) and the reaction mixture was treated to afford the desired compound (720 mg) as a colorless oil.
