Procedure

4-(6-((4-(Methylsulfonyl)piperazin-1-yl)methyl)-2-(2-(tetrahydro-2H-pyran-2-yl)-2H-indazol-4-yl)thieno[2,3-d]pyrimidin-4-yl)morpholine 21 (500 g, 0.836 mole) was charged to a sizable reactor, followed by methanol (9.5 L) and water (250 ml). The resulting slurry was cooled to 0° C. and stirred for 0.5 h. A cold solution of concentrated sulfuric acid (H2SO4, 5.54 ml, assay 95-98%, 1.004 mole, 1.20 equiv.) and water (250 ml) was slowly added while maintaining the temperature below 10° C. The mixture was allowed to warm up to the ambient temperature and stirred for 20 hours. The slurry was cooled to 5° C., filtered and rinsed with cold methanol (2 L). The cake was charged to a reactor and stirred in a mixture of methanol (9.5 L) and water (25 ml) at 50° C. for 3 hours. The slurry was cooled 0-5° C., filtered and rinsed with cold methanol (2 L). The cake was dried in a vacuum oven at 50° C. for 24 hours to afford 4-(2-(1H-Indazol-4-yl)-6-((4-(methylsulfonyl)piperazin-1-yl)methyl)thieno[2,3-d]pyrimidin-4-yl)morpholine II sulfate salt as a light yellow solid (482 g, 94%). 1H NMR (300 MHz, DMSO-d6) 3.00-4.00 (br, 8H), 3.01 (s, 3H), 3.85-3.87 (m, 4H), 4.00-4.02 (m, 4H), 4.69 (s, 2H), 7.46-7.52 (t, 7.8 Hz, 1H), 7.70-7.73 (d, 8.3 Hz, 1H), 7.91 (br, 1H), 8.22-8.25 (d, 7.2 Hz, 1H), 8.82 (s, 1H). LCMS (ESI pos) m/e 514 (M+1).
