5-(2,6-Dimorpholinopyrimidin-4-yl)-4-(trifluoromethyl)pyridin-2-amine hydrochloride hydrate → Buparlisib Hydrochloride

Participants

Reaction Steps

40 mg of 5-(2,6-Di-4-morpholinyl-4-pyrimidinyl)-4-(trifluoromethyl)pyridin-2-amine monohydrate monohydrochloride of Example 6 is equilibrated in 0.5 mL isopropyl acetate in a vial at 25° C.±0.1 for 24 hours equilibration time (with constant agitation). The resulting solids are collected by filtration, air-dried to remove residual excess solvent and then analyzed by X-ray powder diffraction to yield Polymorph Form SC of the monohydrochloride salt of the compound of Formula A.
