1,1'-Carbonyldiimidazole → (3S)-N-(3-((2-chloro-5-fluoropyrimidin-4-yl)amino)-5-methylcyclohexyl)-3-fluoropyrrolidine-1-carboxamide

Participants

Reaction Steps

To a solution of AP-(2-chloro-5-fluoropyrimidin-4-yl)-5-methylcyclohexane-1,3-diamine, 76b, (0.14 g. 0.54 mmol) in THF (2.5 ml) was added carbonyldiimidazole (0.10 g, 0.60 mmol) and iPr2NEt (0.28 mL, 1.62 mmol). The reaction was aged 2 hours at room temp, and treated with (S)-3-fluoropyrrolidine hydrochloride (0.07 g, 0.54 mmol). The reaction was stirred at room temperature for 2 days and then concentrated to dryness to afford 202 mg of (3S)— N-(3-((2-chloro-5-fluoropyrimidin-4-yl)amino)-5-methylcyclohexyl)-3-fluoropyrrolidine-1-carboxamide which was used without purification: LCMS RT=2.46 (M+1) 374.2, (M−1) 372.
