4-(Diethoxyphosphoryl)butanoic acid → HCID 90370178, compound

Participants

Reaction Steps

By using 550 mg of methyl 4-{2-[4-({[2-({3-[(isopropylamino)methyl]benzoyl}amino)-4,5,6,7-tetrahydro-1-benzothiophen-3-yl]carbonyl}amino)phenyl]ethyl}benzoate and 200 mg of 4-(diethoxyphosphoryl)butanoic acid as starting materials, the reaction similar to Preparation Example 27 was performed, thereby obtaining 600 mg of methyl 4-[2-(4-{[(2-{[3-({[4-(diethoxyphosphoryl)butanoyl](isopropyl)amino}methyl)benzoyl}amino}-4,5,6,7-tetrahydro-1-benzothiophen-3-yl)carbonyl]amino}phenyl)ethyl]benzoate.
