Reaction Steps

A mixture of Example 84A (0.359 g, 1.07 mmol), HOBt (0.218 g, 1.61 mmol), EDC (0.308, 1.61 mmol), cyclohexylamine (0.18 mL, 1.61 mmol), and Et3N (0.22 mL 1.61 mmol) in DMF (8 mL) was stirred at room temperature overnight. The reaction mixture was diluted with EtOAc and washed with NaHCO3 and brine. The organic layer was dried over MgSO4 filtered, concentrated, and triturated with ether to give 0.216 g (50%) of the desired product as yellow solid. MS (DCI/NH3) m/z: 408.0 (M+H)+; 1H NMR (300 MHz, DMSO46) δ ppm 1.09-1.44 (m, 5H) 1.58-1.91 (m, 5H) 3.48-3.67 (m, 2H) 3.77 (m, 1H) 7.61 (m, 1H) 7.86 (d, J=7.46 Hz, 1H) 8.02 (s, 1H) 8.23 (d, J=8.14 Hz, 1H) 13.27 (s, 0.5H) 13.58 (s, 0.5H).
