YieldReaction ConditionsOperation in experiment
99% With triethylamine; In methanol; for 2h;Reflux; Example 5: Synthesis of 3-(4-chlorophenyl)-4-cyano-N-methyI-5-morpholin-4- yIthiophene-2-carboxamide (69) ;<n="51"/>69[00150] Step 1: methyl 3-amino-4-cyano-5-(methylsulfanyl)thiophene-2-carboxylate[00151] ; A mixture of [bis(methylsulfanyl)methylene]malononitrile (40 g, 230 mmol), methylthioglycolate (21 mL, 230 mmol) and TEA (24 mL, 173 mmol) in MeOH (600 mL) was allowed to stir at reflux for 2 h. The reaction mixture was allowed to cool overnight and the precipitate was filtered off, washed with cold MeOH (x3) to give methyl 3-amino-4-cyano-5-(methylsulfanyl)thiophene-2- carboxylate (52.4 g, 99 %). LCMS: (AA) ES+ 229.2. 1H NMR (400 MHz, J6-DMSO) δ: 3.74s, 3H) and2.70 (s, 3H).
