To a solution of 4-[2-chloro-5-(5-isopropyl-2-methyl-phenoxymethyl)-6-methyl-pyrimidin-4-yl]-piperazine-1-carboxylic acid tert-butyl ester (500 mg, 1.05 mmol) in DCM (5 mL) is added trifluoroacetic acid (1 mL) with magnetic stirring. Gas evolution is observed and continues for ˜20 min. The light yellow colored solution is evaporated at reduced pressure, diluted with DCM (20 mL) and evaporated again. Placed under high vacuum (˜0.2 Torr) for 20 min to obtain the title compound as a colorless oil. LC/MS (Method 2), M+H=432.1, Rt=1.46 min.
