Reaction Steps

To a solution (1-(1-(5-ethylpyrimidin-2-yl)piperidin-4-yl)-5-(trifluoromethyl)-1H-pyrazol-4-yl)methanol (0.13 g, 0.366 mmol) in dichloromethane (3 mL) was added thionyl chloride (1.2 mL) and the solution was stirred at room temperature for 2 h. The reaction was concentrated in vacuo and the crude product was used in the next step without further purification.
