Reaction Steps

To a solution of 8-chloro-1-methyl-3,4-dihydro-1H-pyrimido[1,6-a]pyrimidin-6(2H)-one (31 mg, 0.153 mmol) and 5-(hydroxymethyl)-2-(3-(trifluoromethyl)phenoxy)benzonitrile (49.4 mg, 0.168 mmol) in N, N-dimethylformamide (DMF) (1.5 mL), was added NaH (18.36 mg, 0.459 mmol). The reaction mixture was stirred at rt for 30 min. Aqueous HCl solution was added to adjust pH to ˜7. Purification by Mass Directed AutoPrep (MDAP) afforded the title compound as a white solid (35 mg, 50% yield).
