Procedure

To a solution of 4-(4-(2-(1-(5-propylpyrimidin-2-yl)piperidin-4-yloxy)benzo[d]thiazol-6-yl)-5,6-dihydropyridin-1(2H)-ylsulfonyl)butanoic acid (30 mg, 0.051 mmol), HOBT (10.2 mg, 0.067 mmol), and EDC (12.8 mg, 0.067 mmol) in CH2Cl2 (1 mL) was added 1-amino-2-methylpropan-2-ol (6.9 mg, 0.077 mmol) followed by slow addition of Et3N (0.03 mL, 0.205 mmol). The reaction mixture was stirred at rt overnight. The reaction mixture was diluted with CH2Cl2 (2 mL), washed with water (2 mL), then brine. The organic layer was dried (Na2SO4), filtered, and concentrated. The residue was recrystallized from 10% water in CH3CN to afford N-(2-hydroxy-2-methylpropyl)-4-(4-(2-(1-(5-propylpyrimidin-2-yl)piperidin-4-yloxy)benzo[d]thiazol-6-yl)-5,6-dihydropyridin-1(2H)-ylsulfonyl)butanamide (24 mg, 0.035 mmol, 68% yield) as a white solid. 1H NMR (500 MHz, CDCl3) δ 8.17 (s, 2H), 7.63 (d, J=2.2 Hz, 1H), 7.62 (d, J=4.1 Hz, 1H), 7.38 (dd, J=8.5, 1.7 Hz, 1H), 6.06 (dt, J=3.2, 1.8 Hz, 1H), 6.04-5.99 (m, 1H), 5.45 (tt, J=7.9, 3.8 Hz, 1H), 4.22 (ddd, J=13.3, 6.9, 4.0 Hz, 2H), 4.02 (q, J=2.6 Hz, 2H), 3.73-3.62 (m, 2H), 3.57 (t, J=5.6 Hz, 2H), 3.28 (d, J=6.1 Hz, 2H), 3.10 (t, J=7.0 Hz, 2H), 2.70-2.64 (m, 2H), 2.49 (t, J=6.7 Hz, 2H), 2.41 (t, J=7.4 Hz, 2H), 2.26-2.14 (m, 5H), 1.94 (dtd, J=12.8, 8.3, 3.9 Hz, 2H), 1.62-1.55 (m, 2H), 1.23 (s, 6H), 0.94 (t, J=7.3 Hz, 3H).
