Reaction Steps
To a solution of methyl 3-amino-4-cyano-5-morpholin-4-ylthiophene-2-carboxylate (3.4 g, 12.6 mmol) in ACN (110 mL) was added diiodomethane (10.5 mL, 130.2 mmol) and amyl nitrite (1.1 mL, 77.7 mmol). The reaction mixture was allowed to stir at 80° C. for 4 days and was concentrated. The residue was purified by column chromatography to give methyl 4-cyano-3-iodo-5-morpholin-4-ylthiophene-2-carboxylate (2.2 g, 46%). LCMS: (FA) ES+ 379.0. 1H NMR (400 MHz, d6-DMSO) δ: 3.76 (s, 3H), 3.72-3.75 (m, 4H) and 3.56-3.61 (m, 4H).
