Reaktionsschritte
The title compound was prepared by a procedure similar to that described for E1 starting from 8-chloro-1-methyl-3,4-dihydro-1H-pyrimido[1,6-a]pyrimidin-6(2H)-one and 5-(hydroxymethyl)-2-5 ((5-(trifluoromethyl)pyridin-2-yl)oxy)benzonitrile. An exemplary process is shown as below: To a solution of 5-(hydroxymethyl)-2-((5-(trifluoromethyl)pyridin-2-yl)oxy)benzonitrile (0.108 mL, 0.601 mmol) in N,N-dimethylformamide (DMF) (5 mL) was added NaH (48.1 mg, 1.202 mmol) and stirred for 10 mins. Then 8-chloro-1-methyl-3,4-dihydro-1H-pyrimido[1,6-a]pyrimidin-6(2H)-one (80 mg, 0.401 mmol) was charged and stirred for 45 mins at rt. The resulting solution was 10 quenched by addition of 1 mL aq. NH4Cl and the solution was filtered. The resulting solution was submitted for MDAP to afford the desired product as a white solid.
