Participants

Reaction Steps

The title compound of Example 238 (63 mg, 0.14 mmol) was dissolved in DMF (1.4 mL) and then sodium tert-butoxide (15 mg, 0.15 mmol) followed by iodomethane (9 μL, 0.14 mmol) were added. After 15 h at room temperature the reaction mixture was diluted with EtOAc and water was added. The aqueous phase was extracted twice with EtOAc and the combined organic phases were dried over MgSO4, filtered and evaporated. Purification was performed using Agilent prep method X to give the title compound (40 mg, 62%).
