Participants

Procedure

3-Phenyl-thiophen-2-ylamine (73 mg, 417 μmol, Int1.1), NEt3 (84.3 mg, 116 μL, 833 μmol) and 1-cyclopentene-1,2-dicarboxylic anhydride (144 mg, 1.04 mmol) were dissolved in dry THF (3 mL). The green-yellow suspension was stirred at RT over the week-end and filtered. The filtrate was concentrated in vacuo and the residue was purified by preparative HPLC (MeOH/H2O with 0.1% formic acid) to give the title compound as a yellow oil (47 mg, 32%, purity estimated at 90%). MS (ESI): m/z=312.2 [M−H]−.
