Ammonium formate → Cyclohexyl 6-(cyclohexyloxy)pyrimidine-4-carboxylate

Participants

Reaction Steps

(13.40 g; 212 mmol) in water (30 ml). A suspension of palladium on calcium carbonate (754 mg; 0.71 mmol) in IPrOH (144 ml) and was treated with 7.5 mL of ammonium formate solution and with cyclohexyl 2-chloro-6-(cyclohexyloxy)pyrimidine-4-carboxylate (4.80 g; 14.2 mmol). After 10 min, a second aliquot of 7.5 mL of ammonium formate solution was added and the mixture was stirred at room temperature for 24 h. The mixture was filtered through a pad of celite and rinsed with MeOH. Solvents were concentrated under vacuum. The crude was dissolved in DCM and washed with water and brine. Organic phase was dried over MgSO4, filtered off and concentrated under vacuum to afford the title compound as an orange solid without further purification.
