The product of Example 101A (cis-2-(3-piperidin-1-yl-cyclobutyl)-benzothiazole-6-ylamine) (50 mg, 0.174 mmole), 5-bromopyrimidine (42 mg, 0.264 mmole), tris(dibenzylideneacetone)dipalladium (0) (6.5 mg, 0.007 mmole), racemic-2,2′-bis(diphenylphosphino)-1,1′-binaphthyl (BINAP, 8.7 mg, 0.014 mmole) and sodium tert-butoxide (23 mg, 0.242 mmole) were charged in a tube and sealed. The tube was placed on high vacuum for 2 hours and refilled with nitrogen. Toluene (2 mL) was added and the reaction vessel was placed in a microwave reactor and heated at 145° C. for 15 minutes. After cooling to room temperature, the mixture was diluted with water and extracted three times with dichloromethane. The combined organic layers were concentrated and the crude product was purified by column chromatography (0.4% ammonium hydroxide and 4% methanol in dichloromethane). The product collected was a mixture of cis and trans isomers. 1H NMR (400 MHz, CDCl3) δ ppm 8.79 (s, 1H) 8.50-8.56 (m, 2H) 7.89 (d, J=8.90 Hz, 1H) 7.58 (d, J=2.15 Hz, 1H) 7.18 (dd, J=8.59, 2.15 Hz, 1H) 5.83 (s, 1H) 3.48-3.63 (m, 1H) 2.73-2.85 (m, 1H) 2.59-2.71 (m, 2H) 2.23-2.39 (m, 6H) 1.54-1.66 (m, 4H) 1.41-1.51 (m, 2H).
