Diisopropylethylamine → HCID 68756823, compound

Participants

Reaction Steps

To a solution of 2-amino-4-methylthiophene-3-carboxamide (1 g, 6.4 mmol) and 2-(4-iodophenyl)acetic acid (1.83 g, 7.0 mmol) in methylene chloride (10 mL) was added Hunig's base (i.e., N,N-diisopropylethylamine) (3.1 mL, 18 mmol) and HATU (2.66 g, 7.0 mmol). The heterogeneous mixture was stirred for 18 h. The reaction was quenched by addition of saturated aqueous ammonium chloride solution and the biphasic mixture was extracted with additional methylene chloride. The organic layer was washed with brine, dried over sodium sulfate and concentrated under reduced pressure to provide a pale brown solid. LCMS method [2]: rt=2.02 min; M+Na 423.0. Material was used without further purification.
