Participants

Reaction Steps

To a mixture of 6.9 g of methyl 4-[2-(4-{[(2-amino-4,5,6,7-tetrahydro-1-benzothiophen-3-yl)carbonyl]amino}phenyl)ethyl]benzoate, 1.5 mL of pyridine and 69 mL of methylene chloride was added dropwise 3.27 g of 3-(chloromethyl)benzoyl chloride, followed by stirring for 1 hour at room temperature. The reaction mixture was concentrated under reduced pressure, ethanol was added thereto, and the precipitated solid was collected by filtration, thereby obtaining 9.27 g of methyl 4-[2-(4-{[(2-{[3-(chloromethyl)benzoyl]amino}-4,5,6,7-tetrahydro-1-benzothiophen-3-yl)carbonyl]amino}phenyl)ethyl]benzoate.
