Reaction Steps

Charge 4,6-dichloro-pyrimidine-5-carbaldehyde (2.5 g, 1.0 eq) and toluene (50 mL) in a round bottom flask. Cool the reaction mass to −10° C. Add ethyl magnesium bromide (3M) in THF solution (5.1 mL, 1.1 eq) drop wise at −10° C. Slowly allow the reaction mass to come to RT in 1 h. Charge chilled ammonium chloride solution to the reaction mass and extract with diethyl ether. Wash ether layer with saturated aq. sodium chloride solution. Dry the ether layer over anhydrous sodium sulfate and concentrated it under reduced pressure to get the desired product (2.3 g, 79.3%).
