Participants

Reaction Steps

Prepared according to the procedure for N-(2-methyl-2-{[5-(trifluoromethyl)pyrimidin-2-yl]amino}cyclopentyl)-3-(pyrimidin-2-yl)pyridine-2-carboxamide (Example 153) from 1-methyl-1-N-[5-(trifluoromethyl)pyridin-2-yl]cyclopentane-1,2-diamine (Intermediate 51; 91 mg, 0.35 mmol), 3-(pyrimidin-2-yl)pyridine-2-carboxylic acid (CAS number 1228431-21-7; 85 mg, 0.42 mmol) and triethylamine (0.147 ml, 1.06 mmol) except after work-up the organics were loaded directly on to a cation/anion mixed mode cartridge, eluted with DCM then with 2M ammonia in methanol and concentrated in vacuo. The resulting residue was purified by reverse phase chromatography (C18 silica, 5-100% water (0.05% ammonia)/acetonitrile) then recrystallised from MTBE/heptane to afford the title compound.
