Reaction Steps
A mixture of the compound from Example 2A (70 mg, 0.31 mmol), 5-chloro-2-methoxy-benzoic acid (64 mg, 0.34 mmol), O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (HATU) (185 mg, 0.46 mmol) and triethylamine (130 L, 0.93 mmol) in N,N-dimethylformamide (5 mL) was stirred at room temperature for 12 hour. The mixture was diluted with water, and extracted with ethyl acetate (3×30 mL). The combined organic layers were dried over MgSO4, filtered and concentrated under reduced pressure. The residue was purified by flash chromatography (silica gel, eluting with ethyl acetate/hexanes 2:3) to provide the title compound. 1H NMR (300 MHz, DMSO-d6) δ ppm 0.95-1.01 (m, 2H) 1.14-1.21 (m, 2H) 1.67-1.78 (m, 1H) 1.79-1.93 (m, 2H) 1.91-2.00 (m, 1H) 2.30-2.39 (m, 1H) 3.65 (dd, J=13.81, 7.06 Hz, 1H) 3.77 (dd, J=13.50, 6.75 Hz, 1H) 3.80 (s, 3H) 4.21 (dd, J=13.20, 4.60 Hz, 1H) 4.31-4.38 (m, 1H) 4.43 (dd, J=12.89, 7.36 Hz, 1H) 7.13 (d, J=8.90 Hz, 1H) 7.49 (dd, J=8.90, 2.76 Hz, 1H) 7.73 (d, J=2.76 Hz, 1H); MS (ESI+) m/z 394 (M+H)+.
