Reaction Steps

4-Cyano-3-(2,4-dichlorophenyl)-5-morpholin-4-yl-N-(tetrahydro-2H-pyran-2-yloxy)thiophene-2-carboxamide (0.050 g, 0.10 mmol) was dissolved in DCM (3 mL) and TFA (0.24 mL, 3.11 mmol) was added. The solution was stirred at room temperature overnight. Solvent was evaporated and the residue was purified by column chromatography (silica gel, elution with DCM to 10% MeOH in DCM over 20 minutes) to give the title compound 24 (0.030 g, 67%). LCMS: (FA) ES+ 398.
