Reaction Steps

In a microwave tube was added 1 eq. of ethyl 2,4-dichloropyrimidine-5-carboxylate (200mg, 0.91 mmol), 0.5 eq. of 3-chlorophenyl boronic acid (67 mg), 0.1 eq. of Pd2(dba)3 (83 mg), 3 eq. of K3PO4 in 4 mL of Dioxane. To this solution was added 1 eq. of tri-(t-butyl) phospine. The reaction was heated in the microwave to 160° C./300 W/for 1200 sec. The crude product was purified by prep HPLC. ES+=296.8.
