Reaction Steps

A 10 mL, CEM microwave vial was charged with N-(6-(6-chloropyrazin-2-yl)benzo[d]thiazol-2-yl)acetamide (0.0657 g, 0.22 mmol), 3-aza-bicyclo[3.2.2]nonane (0.032 g, 0.26 mmol), 1 mL dry TFE and a stirbar. The vessel was flushed with Ar, sealed and heated using a 110° C. heat block for 12 h. The reaction was cooled and 4 mL EtOH was added. The vial was sealed and the slurry was heated to 140° C. using a heat transfer block for 5 minutes and cooled. The slurry was filtered using a course glass filter fitted with a 0.22 μm teflon filter. The solid was dried at 60° C. and <1 mm Hg for 3 h and then dissolved in warm DMF. The turbid solution was filtered through a 0.22 μm teflon filter, and the solvent was removed in vacuo to afford 6-(6-(3-aza-bicyclo[3.2.2]nonan-3-yl)pyrazin-2-yl)benzo[d]thiazol-2-amine (19 mg). 1H NMR (400 MHz, Pyr) δ ppm 1.48-1.68 (m, 8H) 2.01 (s, 2H) 3.83 (d, J=4.11 Hz, 4H) 7.92 (dd, J=8.41, 0.39 Hz, 1H) 8.28 (dd, J=8.41, 1.86 Hz, 1H) 8.34 (s, 1H) 8.71 (s, 1H) 8.75 (dd, J=1.37, 0.49 Hz, 1H) 8.89 (s, 2H). 13C NMR (101 MHz, Pyr) δ ppm 25.05 (s, 4 C) 30.68 (s, 2 C) 53.39 (s, 2 C) 118.92 (s, 1 C) 119.97 (s, 1 C) 125.11 (s, 1 C) 128.54 (s, 1 C) 128.71 (s, 1 C) 131.27 (s, 1 C) 133.33 (s, 1 C) 149.01 (s, 1 C) 155.03 (s, 1 C) 155.42 (s, 1 C) 169.00 (s, 1 C).
