Reaction Steps

A solution of (1S,4R)-4-{5-[3-(aminomethyl)-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl]-1,3-thiazol-2-yl}-4-hydroxy-2,2-dimethylcyclohexanecarboxylic acid (40 mg, 0.075 mmol) in anhydrous THF (5 ml) was added acetic acid (6.41 μl, 0.112 mmol, 1.5 equiv), EDC (21.48 mg, 0.112 mmol, 1.5 equiv), HOBt (17.16 mg, 0.112 mmol, 1.5 equiv) and then triethylamine (0.031 ml, 0.224 mmol, 3.0 equiv). The mixture was stirred at 23° C. for 14 h. The reaction mixture was partitioned between EtOAc (2×40 ml) and water (45 ml). The combined organic layers were dried over Na2SO4 and concentrated, affording the desired product, methyl (1S,4R)-4-[5-(3-[(acetylamino)methyl]-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]-4-hydroxy-2,2-dimethylcyclohexanecarboxylate (40 mg, 74%) as a yellow oil. 1H NMR (500 MHz, DMSO) 10.3 (s, 1H), 8.83 (d, J=4.9 Hz, 1H), 8.38 (m, 1H), 8.02 (bs, 1H), 7.90 (s, 1H), 7.68-7.66 (m, 2H), 7.52 (s, 1H), 7.28 (d, J=4.9 Hz, 1H), 5.94 (s, 1H), 4.24 (d, J=5.9 Hz, 2H), 4.12 (t, J=5.8 Hz, 1H), 3.60 (s, 3H), 3.31 (m, 2H), 1.97-1.88 (m, 5H), 1.75-1.73 (m, 2H), 1.24-1.22 (m, 6H).
