실험 절차

To a solution of 10 g (45.11 mmol) of 4-trifluoromethyl-pyrimidin-2-ylamine and 0.065 g of palladium 10 wt. % on activated carbon in 5 ml of isopropanol was added 45 ml of a solution of hydrochloric acid in isopropanol (5–6 N). The mixture was shaken at 40° C. under hydrogen pressure of 4 atmospheres until hydrogen uptake ceased. The catalyst was removed by filtration and washed with isopropanol. The filtrate was evaporated to dryness to afford 12.14 g of pure product as a white solid.
