Procedure: A suspension of 26.4 g of ethyl 2,3,4,5-tetrafluorobenzoylacetate, 18.7 g of 2-(dimethylaminomethyl)morpholine and 8.4 g sodium hydrogencarbonate in 130 ml of acetonitrile is refluxed for 7 hours. The reaction mixture is concentrated under reduced pressure, to the obtained residue is added 100 ml of chloroform and the solution is washed with water. After drying over anhydrous magnesium sulfate, the chloroform is distilled off under reduced pressure and the residue is purified by chromatography on silica gel to give 29.9 g of ethyl 4-[2-(dimethylaminomethyl)morpholino]-2,3,5-trifluorobenzoylacetate in 77% yield as an oily substance. is refluxed for 7 hours The reaction mixture is concentrated under reduced pressure, to the obtained residue is added 100 ml of chloroform the solution is washed with water After drying over anhydrous magnesium sulfate the chloroform is distilled off under reduced pressure the residue is purified by chromatography on silica gel

Procedure: A mixture of racemic 2-dimethylaminomethylmorpholine (670 mg, 4.65 mmol), 6-amino-4-fluoronicotinonitrile (intermediate 21, 637 mg, 4.65 mmol) and triethylamine (2.59 ml, 18.6 mmol) was heated at 60° C. in a septum sealed reaction vessel under argon for 10 h. The reaction mixture was evaporated, partitioned between aq. hydrochloric acid (2 M) and DCM (2×), the aqueous layer basified with aqueous NaHCO3, extracted a further 10× with DCM containing 10% MeOH, the combined DCM layers from the basic extraction, dried over Na2SO4 and evaporated. The residue was applied to a 24 g RediSep® silica column as a DCM solution and purified by normal phase chromatography, eluting with a gradient from DCM to 20% MeOH in DCM. Product containing fractions were combined and evaporated to give the title compound as a beige foam.
