Versuchsvorschrift

To a flask was added 4 Å molecular sieves (200 mgs) and the product from Step 1 (0.050 g, 0.14 mmol), 5-(aminomethyl)pyrrolidin-2-one (0.016 g, 0.21 mmol) and a 95:5 solution of DMF: acetic acid (1.4 mL). The mixture was stirred overnight. Resin-bound sodium cyanoborohydride (0.44 g, 0.41 mmol, 0.93 mmol/g loading) was added and the reaction was stirred for 72 hours. The mixture was filtered and purified by reverse phase HPLC (12-100% acetonitrile gradient with water over 6 minutes with 0.1% formic acid buffer) to yield 5-[({[5-(3-methyl-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]methyl}amino)-methyl]pyrrolidin-2-one (0.016 g, 25%). MS ESI: [M+H]+ m/z 463.1. 1H NMR (600 MHz, DMSO-d6) δ 10.22 (s, 1H), 8.81 (d, J=5.2, 1H), 7.96 (s, 2H), 7.61 (s, 1H), 7.42 (s, 1H), 7.26 (d, J=5.1, 1H), 7.14 (s, 1H), 4.03 (s, 2H), 3.63 (s, 1H), 2.74-2.53 (m, 1H), 2.47 (m, 1H), 2.29 (s, 3H), 2.20-1.98 (m, 3H), 1.80-1.59 (m, 1H). rhSYK activity=+++
