1,3-Thiazol-2-ylmethanol → Ethyl 5-trifluoromethyl-1-[(thiazol-2-yl)methyl]-1H-pyrrolo[2,3-b]pyridine-2-carboxylate

Participants

Reaction Steps

This compound was prepared according to a process similar to that described in step 5.1. by reacting 390 mg (1.51 mmol) of ethyl 5-trifluoromethyl-1H-pyrrolo[2,3-b]pyridine-2-carboxylate (WO2008/107543) with 348 mg (3.02 mmol) of thiazol-2-ylmethanol in the presence of 0.92 g (3.826 mmol) of (cyanomethylene)-tributylphosphorane (CMBP). The reaction mixture is then purified by flash chromatography on a column of silica gel in a mixture of heptane and ethyl acetate to give 446 mg of the expected product in the form of an oil.
