Reaction Steps

To a solution of N-(2-amino-4,4-difluorocyclopentyl)-2-(2H-1,2,3-triazol-2-yl)benzamide hydrochloride (Intermediate 42; 120 mg, 0.39 mmol) in dry DMSO (1.2 ml) was added 2-chloro-5-(trifluoromethyl)pyrimidine (CAS number 69034-12-4; 70 mg, 0.384 mmol) and DIPEA (183 μl, 1.047 mmol). The reaction mixture was heated in a sealed vial at 140° C. for 17 hours then partitioned between ethyl acetate and water. The organics were washed with water, filtered through a hydrophobic frit and concentrated in vacuo. The crude material was purified by column chromatography (basic silica, 0-100% ethyl acetate/petrol) then was chirally separated using SFC (Waters prep30/MS system using 20% Isopropanol, Daicel AD 10 mm id×250 mm long columns at 30 ml/min, 40° C. and 100 bar) to afford the title compound as a single enantiomer.
