Participants

Reaction Conditions

Reaction Steps

A cold (0° C.) solution of cyclohexanol (3.82 ml; 36.2 mmol) was treated with sodium hydride (869 mg; 36.2 mmol) in dry THF (100 ml) and stirred for 30 min at 0° C. It was slowly added to a cooled (0° C.) solution of methyl 2,4-dichloropyrimidine-6-carboxylate (Apollo, 10.00 g; 48.3 mmol) in dry THF (200 ml) and the resulting mixture was stirred for 24 h. The reaction mixture was concentrated under vacuum. The residue was taken up in EtOAc and the organic layer was washed with water, then brine, dried over MgSO4, filtered off and concentrated under vacuum to afford a crude which was purified by flash chromatography eluting with cHex-EtOAc 8:2 to afford the title compound as a white solid.
