実験手順
Amorphous tofacitinib hydrobromide (0.55 g) was dissolved in water (6 mL). The solution was treated with solid monosodium citrate (0.40 g, 1.69 mmol) and the resulting white suspension was stirred for 16 hours at 25° C. The suspension was filtered, washed with water (2×5 mL) and air-dried for 16 hours at 25° C. to yield 0.63 g of tofacitinib citrate as a white solid.
