The product from Step 2 (80 mg, 0.172 mmol) was taken up in THF (2 mL) in a microwave vial, and Burgess reagent (82 mg, 0.344 mmol) was added. The reaction was irradiated in the microwave at 100° C. for 30 min. The yellow reaction mixture was concentrated to dryness, and the resulting residue was purified by column chromatography on silica (0-100% ethyl acetate in hexanes) to provide N-(3-methyl-5-{2-[2-(1,3,4-oxadiazol-2-yl)propan-2-yl]-1,3-thiazol-5-yl}phenyl)-4-(trifluoromethyl)pyrimidin-2-amine (32 mg, 42%) as an off-white solid. MS ESI: [M+H]+ m/z 447.0. 1H NMR (600 MHz, DMSO-d6) δ 10.24 (s, 1H), 9.20 (s; 1H), 8.81 (d, J=4.9, 1H), 7.97 (s, 2H), 7.44 (s, 1H), 7.26 (d, J=4.9, 1H), 7.14 (s, 1H), 2.29 (s, 3H), 1.87 (s, 6H). rhSYK activity=+++
