1,8-Diazabicyclo(5.4.0)undec-7-ene → [4-(2,4-Dioxo(1,3-dihydroquinazolin-3-yl))phenyl]-n-[(5-chloro(2-thienyl))sulfonyl]carboxamide

Participants

Reaction Steps

A 44 mg portion (0.14) of (4-aminophenyl)-N-[(5-chloro(2-thienyl))sulfonyl]carboxamide was combined with 25 mg (0.14 mmol) of methyl 2-isocyanatobenzoate in 500 uL of THF followed by the addition of 1 equivalent of TEA (24 μL) and 1 equivalent of DBU.
