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.
