Reaction Steps

A mixture of (R)-2-(3-(piperidin-1-yl)pyrrolidin-1-yl)benzo[d]thiazol-6-ol (Example 47, 40 mg, 0.132 mmol), 3-chloro-6-methoxypyridazine (28.6 mg, 0.198 mmol), palladium(II) acetate (2.96 mg, 0.013 mmol), and potassium phosphate tribasic (84 mg, 0.40 mmol) in toluene (1 mL) was heated at 100° C. over night, cooled, diluted with 1 M NaOH (5 mL) and extracted with CH2Cl2 (2×25 mL). The combined CH2Cl2 layers were dried (MgSO4), filtered, concentrated and chromatographed on silica gel eluting with a gradient of 2-10% (9:1 methanol:ammonium hydroxide) in CH2Cl2 to provide the title compound. 1H NMR (300 MHz, CDCl3) δ ppm 1.43-1.53 (m, 2H), 1.58-1.69 (m, 4H), 1.94-2.09 (m, 1H), 2.25-2.36 (m, 1H), 2.40-2.59 (m, 4H), 2.95-3.07 (m, 1H), 3.42 (t, J=9.2 Hz, 1H), 3.54 (dt, J=10.2, 6.8 Hz, 1H), 3.75 (t, J=8.8 Hz, 1H), 3.81-3.89 (m, 1H), 4.04 (s, 3H), 7.02 (d, J=9.2 Hz, 1H), 7.11 (dd, J=8.5, 2.4 Hz, 1H), 7.13 (d, J=9.5 Hz, 1H), 7.49 (d, J=2.7 Hz, 1H), 7.56 (d, J=8.8 Hz, 1H); MS (DCI/NH3) m/z 412 (M+H)+.
