Reaction Steps

To 5-(3-methyl-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazole-2-carbaldehyde (Example 88, Step 1, 0.15 g, 0.41 mmol) was added methanol (4 mL) and sodium borohydride (0.016 g, 0.41 mmol). Once complete, the reaction was diluted with ethyl acetate, washed carefully with aqueous saturated ammonium chloride, dried over magnesium sulfate, filtered and concentrated. The crude product was purified by silica gel column chromatography to yield [5-(3-methyl-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]methanol (0.13 g, 85%). MS ESI: [M+H]+ m/z 366.7. 1H NMR (500 MHz, DMSO-d6) δ 10.26 (s, 1H), 8.83 (d, J=4.8, 1H), 7.98 (s, 2H), 7.45 (s, 1H), 7.28 (d, J=4.9, 1H), 7.17 (s, 1H), 6.10 (t, J=5.8, 1H), 4.71 (d, J=5.8, 2H), 2.31 (s, 3H). rhSYK activity=+++
