実験手順
Under N2, ethyl 1-(6-(trifluoromethyl)pyrazin-2-yl)-1H-pyrazole-4-carboxylate (155 mg, 542 μmol, Eq: 1.00) was dissolved in DMF (9.3 ml) and Water (9.3 ml). Potassium carbonate (150 mg, 1.08 mmol, Eq: 2) was added and the RM was stirred at 70° C. overnight. Control with LC-MS: Pr/SM: 74/26. Potassium carbonate (150 mg, 1.08 mmol, Eq: 2) was added and the RM was stirred at 70° C. overnight. Control with LC-MS: SM/Pr:4/96. At RT, the RM was partitioned between 1M K2CO3 and EtOAc; extracted; the water layer was acidified with 1M HCl; extracted with EtOAc; the organic phase was dried over MgSO4; filtered; concentrated in vacuo leading to 132 mg off-white solid.
