Reaction Steps
A solution of 70 (2.5 g; 9.36 mmol) and methyl 3-aminothiophene-2-carboxylate (1.62 g; 10.30 mmol) in anhydrous pyridine (12.0 mL; 144 mmol) was stirred at room temperature for 12 hours. The reaction mixture was concentrated under reduced pressure and the resulting residue was purified by automated silica gel column chromatography (Biotage®) eluting with ethyl acetate/hexanes (0 to 20% v/v) to give the title compound as a clear oil (1.79 g).
