Versuchsvorschrift

2,4 dichloropyrimidine and 5-formyl-2-methoxyphenylboronic acid was coupled following procedure A. The yield was 70%. LC-MS showed the product was >95% pure and had the expected M+H+ of 249. 1H NMR (Varian 300 MHz, MeOD-d6, shifts relative to the solvent peak at 3.33 ppm) δ 9.9 (s, 1H) 8.7 (d, 1H) 8.4 (s, 1H) 8.0 (d, 2H) 7.4 (d, 1H) 3.9 (s, 3H).
