Procedure

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 triethylamine (0.427 ml, 3.06 mmol) was added, followed by benzoyl chloride (0.215 g, 1.53 mmol). The reaction mixture was stirred 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 provide the title compound (0.072 g, 21.8% yield) as a white powder. 1H NMR (DMSO-d6) δ 2.85 (t, 2H), 3.58 (m, 2H), 5.26 (s, 2H), 6.69 (s, 1H), 6.89 (m, 1H), 7.32-7.59 (m, 9H), 7.82-7.87 (m, 3H), 8.55 (t, 1H), 9.95 (s, 1H).
