Reaction Conditions

Reaction Steps

4,6-Dichloropyrimidine 6 (149 mg, 1.0 mmol) in THF (2 mL) was added to a solution of TMPZnCl.LiCl (2) (1.3 M in THF, 0.85 mL, 1.1 mmol) at 25° C. and the reaction mixture was then stirred at this temperature for 45 min according to TP 2. CuCN.2LiCl (1.0 M solution in THF, 1.1 mL, 1.1 mmol) was slowly added at −20° C. and the reaction mixture was stirred at the same temperature for 30 min. Then, furan-2-carbonyl chloride (261 mg, 2.0 mmol) was dropwise added at −20° C. and the resulting mixture was allowed to warm up slowly to 25° C. overnight. The reaction mixture was quenched with a sat. aq. NH4Cl solution (30 mL), extracted with diethyl ether (5×30 mL) and dried over anhydrous Na2SO4. After filtration, the solvent was evaporated in vacuo. Purification by flash-chromatography (CH2Cl2/n-pentane 1:1) furnished 8b as a colourless solid (172 mg, 71%).
