Reaction Steps

To a microwave vial was added 2-[2-oxo-3-(piperidin-4-ylmethyl)-2,3-dihydro-1,3-benzothiazol-6-yl]benzonitrile (11-3) (0.029 g, 0.075 mmol), 2-bromopyrimidine (0.0143 g, 0.090 mmol), NMP (0.7 mL), and DIPEA (0.033 mL, 0.188 mmol). The reaction mixture was then heated under microwave irradiation at 100° C. for 10 minutes. The crude reaction mixture was then allowed to cool to room temperature, diluted with methanol, filtered and concentrated. Purification of crude reaction mixture by reverse phase chromatography (Waters Sunfire MSC18, 10% acetonitrile/0.1% trifluoroacetic acid/water→100% acetonitrile/0.1% trifluoroacetic acid/water) gave 2-{2-oxo-3-[(1-pyrimidin-2-ylpiperidin-4-yl)methyl]-2,3-dihydro-1,3-benzothiazol-6-yl}benzonitrile (11-4) as a brown solid. HRMS (M+H)+: observed=428.1544, calculated=428.1540.
