To a solution of 2-chloro-4-(3,3-difluoroazetidin-1-yl)-7-(4-fluorophenyl)-6,7-dihydro-5H-cyclopenta[d]pyrimidine (Preparation Ha) (170 mg, 0.500 mmol) and 4-(3-chloro-1H-1,2,4-triazol-1-yl)-3-methoxyaniline (Preparation F) (146 mg, 0.650 mmol) in THF (1498 mL) was added Acetic Acid (1498 mL). The resulting mixture was heated to 100° C. and stirred overnight. The reaction mixture was then concentrated in vacuo. MeOH was added to the residue which resulted in a suspension. This was filtered to give a solid which was taken up in hot MeOH and filtered. The filtrate was then concentrated in vacuo to give N-(4-(3-chloro-1H-1,2,4-triazol-1-yl)-3-methoxyphenyl)-4-(3,3-difluoroazetidin-1-yl)-7-(4-fluorophenyl)-6,7-dihydro-5H-cyclopenta[d]pyrimidin-2-amine (racemate) (130 mg, 49.22% yield) as a yellow solid.
