Procedure
2,4 dichloropyrimidine and 4-methyl-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzaldehyde was coupled following procedure A. The yield was 80%. LC-MS showed the product was >95% pure and had the expected M+H+ of 233. 1H NMR (Varian 300 MHz, CDCl3, shifts relative to the solvent peak at 7.24 ppm) δ 10.0 (s, 1H) 8.7 (s, 1H) 7.9 (d, 2H) 7.5 (d, 2H), 2.5 (s, 3H).
