Participants

Reaction Steps

A flask was charged with 1-carbamoylcyclopropanecarboxylic acid (16.23 mg, 0.126 mmol), N-(3-{2-[amino(dicyclopropyl)methyl]-1,3-thiazol-5-yl}-5-methylphenyl)-4-(trifluoromethyl)-pyrimidin-2-amine (56 mg, 0.126 mmol), BOP (83 mg, 0.189 mmol), DIPEA (43.9 μL, 0.251 mmol) and DMF (10 mL). The reaction was stirred at room temperature for 90 minutes. The mixture was diluted with ethyl acetate, washed with saturated NaHCO3, followed by brine, dried (Na2SO4), filtered, and concentrated to afford N-{dicyclopropyl[5-(3-methyl-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]methyl}cyclopropane-1,1-dicarboxamide (67.6 mg, 0.121 mmol, 97% yield) as an off white solid.
