Diisopropylethylamine → HCID 86627062, compound

Participants

Reaction Steps

A solution (0.13 M) of [5-(4-chlorophenyl)-6-cyclohexyl-3-formyl-2-(methoxycarbonyl)-4H-thieno[3,2-b]pyrrol-4-yl]acetic acid in DMF was treated with DIEA (3 eq.), HATU (1.5 eq.) and a solution (0.5 M) of 1-isopropyl-N-methylpyrrolidin-3-amine (1.5 eq.) in DMF. The reaction mixture was stirred at RT for 3 h. The reaction was quenched with aqueous NaHCO3 (saturated solution) and extracted with AcOEt. The combined organic phase was washed with brine and dried. Evaporation under reduced pressure gave a residue that was purified by flash chromatography on silica gel (1:49 Et3N/AcOEt) to afford the title compound (62%) as a solid.
