Participants

Reaction Steps

6-Amino-nicotinic acid (21.5 mg, 0.155 mmol), HATU (59 mg, 0.155 mmol) and triethylamine (0.05 mL, 0.359 mmol) were mixed in DMF and stirred at rt for 20 min. 4-(2-Fluoro-4-methanesulfonyl-phenoxy)-5-methyl-6-(piperidin-4-yloxy)-pyrimidine was then added and the mixture stirred at rt for 2 h. The crude was purified by HPLC to afford Compound C5 as a yellow solid (67 mg, 90.7%). 1H NMR (CDCl3, 400 MHz) δ 1.88-1.87 (m, 2H), 1.99-2.01 (m, 2H), 2.15 (s, 3H), 3.03 (s, 3H), 3.58-3.60 (m, 2H), 3.77-3.78 (m, 2H), 5.37-5.41 (m, 1H), 6.78-6.82 (d, 1H), 7.33-7.38 (m, 1H), 7.69-7.74 (m, 2H), 7.87-7.96 (m, 2H), 8.14 (s, 1H). Exact mass calculated for C23H24FN5O5S 501.15, found 502.4 (MH+).
