Reaction Steps

A mixture of (R)-2-(3-(piperidin-1-yl)pyrrolidin-1-yl)benzo[d]thiazol-6-ol (Example 47, 20 mg, 0.066 mmol), 6-chloro-N-methylnicotinamide (Example 71A, 11 mg, 0.066 mmol) and K2CO3 (27 mg, 0.20 mmol) in N,N-dimethylformamide (0.25 mL) was heated to 100° C. for 1 hour, cooled, diluted with CH2Cl2, filtered, and concentrated. The residue was purified by HPLC as described in Example 66. The product was further purified by chromatography on silica gel eluting with a gradient of 2 to 10% (9:1 methanol:ammonium hydroxide) in CH2Cl2 to provide the title compound. 1H NMR (300 MHz, CDCl3) δ ppm 1.44-1.53 (m, 2H), 1.59-1.67 (m, 4H), 1.94-2.10 (m, 1H), 2.24-2.34 (m, 1H), 2.39-2.57 (m, 4H), 2.95-3.06 (m, 1H), 3.01 (d, J=4.7 Hz, 3H), 3.43 (t, J=9.3 Hz, 1H), 3.48-3.60 (m, 1H), 3.70-3.89 (m, 2H), 6.09-6.18 (m, 1H), 6.92 (dd, J=8.5, 0.7 Hz, 1H), 7.07 (dd, J=8.5, 2.4 Hz, 1H), 7.40 (d, J=2.4 Hz, 1H), 7.58 (d, J=8.8 Hz, 1H), 8.12 (dd, J=8.6, 2.5 Hz, 1H), 8.53 (dd, J=2.7, 0.7 Hz, 1H); MS (DCI/NH3) m/z 438 (M+H)+.
