Participants

Reaction Steps

To the mixture of methyl 6-amino-5-(5-amino-1-benzothien-2-yl)nicotinate (120 mg, 0.4 mmol, 1 eq) and 3-methylfuranylcarboxylic acid (50.4 mg, 1 eq) in 1,2-dichloroethane (3 mL) at 60° C. was added catalytic amount of DMAP (10 mg, 0.2 eq) and EDCI (92.2 mg, 1.2 eq). The reaction was stirred at that temperature for 2 h and then partitioned between EtOAc and saturated aq NaHCO3. The organic layer was further washed with brine and then dried with anhydrous sodium sulfate. The organic layer was decanted, concentrated, and the solid residue which was treated with ethyl acetate with stirring at room temperature for an hour. Methyl 6-amino-5-{5-[(3-methyl-2-furoyl)amino]-1-benzothien-2-yl}nicotinate was obtained upon filtration as a white solid in amount of 128 mg.
