Reaction Steps

2-Chloro-6-((4-methanesulfonylpiperazin-1-yl)methyl)-4-morpholinothieno[3,2-d]pyrimidine, prepared via General Procedure B-3, (100 mg) was used in General Procedure A using 2-methoxypyridine-5-boronic acid as the boronic acid. The resulting crude (60 mg) was treated with 1 mL of 48% HBr in acetic acid and heated to 125° C. for 6 min in the microwave. The 2-hydroxy pyridine was extracted into ethylacetate and washed with water. After evaporation of the organic layer the crude was purified by reversed phase HPLC purification to yield 17 mg of 189. NMR (CDCl3): 2.67 (m, 4H, 2×CH2), 2.80 (s, 3H, CH3), 3.30 (m, 4H, 2×CH2), 3.87-3.89 (m, 6H, 3×CH2), 3.98-4.00 (m, 4H, 2×CH2), 6.65 (d, H, ArH, J=10.27 Hz), 7.25 (s, H, ArH) 8.50-8.53 (m, 2H, 2×ArH), 11.6 (sbr, H, OH). MS: (ESI+): MH+ 491.22
