Versuchsvorschrift

To a suspension of 4-[3-(4-fluorophenyl)-1H-pyrazol-4-yl]-2-pyrimidinamine prepared in accordance with Example A-306 (0.26 g, 0.001 mol) in 5 mL of pyridine was added ethyl chloroformate dropwise. After the addition, the clear solution was stirred at room temperature for 6 hours. Water was added and the aqueous phase was extracted with ethyl acetate. The organic layer was washed with brine, dried over magnesium sulfate and filtered. The filtrate was concentrated and the crude was trituated with ether to give 0.15 g of product, ethyl [4-[3-(4-fluorophenyl)-1H-pyrazol-4-yl]-2-pyrimidinyl]carbamate, as a white solid (46% yield), mp: 163–165° C.; Anal. Calc'd for C16H14FN5O2: C, 58.71; H, 4.31; N, 21.04. Found: C, 59.22; H, 4.51; N, 21.66.
