Reaction Steps
A mixture of ethyl 4-cyano-3-(2,4-dichlorophenyl)-5-(2-(fluoromethyl)morpholino)thiophene-2-carboxylate (300 mg, 0.00054 mol), Sodium hydroxide (0.12 g, 0.0030 mol) in EtOH (10.0 mL, 0.171 mol) and water (3.0 mL, 0.17 mol) was stirred at it until completion by LCMS. The mixture was concentrated and the residue was acidified by 1NHCl. The precipitate was collected and dried in air and vacuum to afford 4-cyano-3-(2,4-dichlorophenyl)-5-(2-(fluoromethyl)morpholino)thiophene-2-carboxylic acid (225 mg, 99%). LCMS: (FA) ES+ 415, ES− 413.
