Preparation 108A: 5-(Benzo[b]thiophen-7-yl)-4-methylpyrimidine[00353] A vessel capable of sealing was charged with a mixture of 7- bromobenzo[b]thiophene (100 mg, 0.467 mmol), 4-methylpyrimidin-5-ylboronic acid (97 mg, 0.70 mmol), PdCl2(dppf)-CH2Ci2 adduct (19.2 mg, 0.023 mmol), dioxane (3 mL), and a 2.0 M water solution of K3PO4 (0.7 mL, 1.41 mmol) and was purged with nitrogen for 10 min. The vessel was sealed and heated at 100 C for 16 hours. Upon cooling, the reaction mixture was diluted with CH2CI2 and filtered with CH2Cl2/MeOH washing. The filtrate was concentrated under reduced pressure. The residue was dissolved in CH2CI2 and washed with water, brine, dried over anhydrous Na2S04 and concentrated under reduced pressure. The crude material was purified by BIOTAGE eluting with 0%-15% EtOAc/CH2Cl2 at 30 mL/min. Concentration of appropriate fractions provided the title compound (32 mg, 30% yield). LC/MS: Example 108A (at) 2.49 min (RT) (Condition G). MS (ES): m/z=227.07.1 [M+H]+. ? NMR (400 MHz, CDC13) delta ppm 9.19 (1 hr, s), 8.68 (1 hr, s), 7.92 (1 hr, d, J=8.06 Hz), 7.38-7.52 (3 hr, m), 7.23 (1 hr, d, J=7.05 Hz), 2.44 (3 hr, s).
