A solution of EXAMPLE 89 (20 mg, 0.08 mmol), 1-methylcyclopropanecarboxylic acid (10 mg, 0.096 mmol), HATU (2-(1H-7-azabenzotriazol-1-yl)-1,1,3,3-tetramethyl uronium hexafluorophosphate methanaminium) (38 mg, 0.1 mmol) and triethylamine (20 mg, 0.2 mmol) in dimethylacetamide (2.5 mL) was stirred at room temperature for 18 hours, and concentrated. The residue was dissolved in a 1:1 mixture of dimethylsulfoxide/methanol, and separated by HPLC (Waters Sunfire® C-8 analytical column [Milford, Mass.], 0.1% trifluoroacetic acid/water/CH3CN) to provide the title compound. MS (DCI/NH3) m/z 338 (M+H)+; 1H NMR (500 MHz, D2O/dimethylsulfoxide-d6): δ 0.57-0.69 (m, 2H), 1.02-1.10 (m, 2H), 1.38 (s, 3H), 1.57-1.65 (m, 4H), 2.29-2.44 (m, 4H), 3.87 (s, 2H), 6.89 (d, J=7.63 Hz, 1H), 7.23 (t, J=7.93 Hz, 1H), 7.42 (s, 1H), 7.46 (d, J=8.24 Hz, 1H).
