Versuchsvorschrift

Crude 4-(2-aminoethyl)-N-(3-(benzyloxy)pyridin-2-yl)thiazol-2-amine (Example 134, Step A; 0.25 g, 0.766 mmol) was dissolved in DMF (10 mL), and 1-isocyanatobenzene (0.182 g, 1.53 mmol) was added. The reaction mixture was stirred for 2 hours, then partitioned between ethyl acetate and water. The organic layer was washed with water and brine, dried, and concentrated. The residue was purified via MPLC (Biotage) eluting with 2:3 hexane:ethyl acetate to afford the title compound (0.122 g, 35.8% yield) as a light yellow powder. 1H NMR (DMSO-d6) δ 2.75 (t, 2H), 3.42 (q, 2H), 5.27 (s, 2H), 6.19 (t, 1H), 6.70 (s, 1H), 6.86-6.91 (m, 2H), 7.20 (t, 2H), 7.34-7.43 (m, 6H), 7.58 (d, 2H), 7.87 (d, 1H), 8.48 (s, 1H), 9.94 (s, 1H).
