反応手順
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. After 18 h, the mixture was purified by RP-HPLC, to give 21 mg (34%) of the desired compound. ES-MS (M+H)+=462 (Cl).
