Fumaric Acid → 2-tert-butyl-4-[(3-methoxypropyl)amino]-N-(2-methylpropyl)-N-[(3S,5R)-5-(morpholin-4-ylcarbonyl)piperidin-3-yl]pyrimidine-5-carboxamide monofumarate

온도

2-tert-Butyl-4-[(3-methoxypropyl)amino]-N-(2-methylpropyl)-N-[(3S,5R)-5-(morpholin-4-ylcarbonyl)piperidin-3-yl]pyrimidine-5-carboxamide (5.22 g) was dissolved in ethyl acetate (80 ml), and a solution of fumaric acid (1.17 g) in methanol (20 ml) was added. The mixture was heated to 70° C., stirred well and filtered. The filtrate was concentrated under reduced pressure, and the obtained white solid (6.40 g) was suspended in ethyl acetate (190 ml), and dissolved by heating to 70° C. Acetonitrile (190 ml) heated to 70° C. was added, and the mixture was allowed to cool to 50° C. Seed crystals (10 mg) were added, and the mixture was allowed to cool to room temperature with stirring. The mixture was further stirred at 0° C. for 2 hr, and the precipitated white solid was collected by filtration, and washed with ethyl acetate-acetonitrile (1:1). The obtained white crystals were dried under reduced pressure at 100° C. for 12 hr to give the object compound (4.16 g).
