Versuchsvorschrift

To (R)-2-(2-(1H-pyrrolo[2,3-b]pyridin-3-yl)pyrimidin-4-ylamino)-2-methylbutanoic acid (4a) (limiting reagent) charge 2-methylTHF (7.5 vol), then charge T3P® (2.0 eq, 50% w/w in 2-MeTHF). Heat the mixture to 60-65° C. and maintain this temperature for no less than 3 hrs and the solids are completely dissolved. Cool to 20-25° C. then charge 2,2,2-trifluoroethylamine (2.0 eq). Continue agitation for no less than 6 hrs at 20-25° C. and until HPLC analysis showed <1.0% of (R)-2-(2-(1H-pyrrolo[2,3-b]pyridin-3-yl)pyrimidin-4-ylamino)-2-methylbutanoic acid (4a). Slowly charge a Na2CO3 solution (15 vol, 1.165M) while maintaining a batch temperature <30° C. Stir the mixture for 30 min then separate the phases. Wash the organic phase with water (4 vol). Emulsions have been observed at this point and can be addressed through addition of NaCl solution. Charge methanol (7 vol) then distill to 4 vol. Repeat 3 times. Prior to crystallization, adjust the total volume to approximately 11 vol. Heat the mixture to 50-55° C. then add water (2.45 vol, final solvent composition 22% water in methanol) over 30 min. Seed the batch with (R)-2-(2-(1H-pyrrolo[2,3-b]pyridin-3-yl)pyrimidin-4-ylamino)-2-methyl-N-(2,2,2-trifluoroethyl)butanamide (Ia) (1 wt % seed based on the compound of Formula (4a)). Stir for 4 hrs at 50-55° C. then add water over 24 h until the mixture is approximately 58 wt % water in methanol. Cool to 20-25° C., stir 1 h, then filter. Wash the cake with water (2 vol). Dry the solids at 60-65° C. to give (R)-2-(2-(1H-pyrrolo[2,3-b]pyridin-3-yl)pyrimidin-4-ylamino)-2-methyl-N-(2,2,2-trifluoroethyl)butanamide (Ia).
