N,N,N′,N′-Tetramethyl-0-(7-azabenzotriazol-1-yl)uronium Hexafluorophosphate (1.19 g, 3.14 mmol) added to a solution of 3-(3-((((3aR,4R,6R,6aS)-6-(4-((2,4-dimethoxybenzyl)amino)-7H-pyrrolo[2,3-d]pyrimidin-7-yl)-2,2-dimethyltetrahydro-3aH-cyclopenta[d][1,3]dioxol-4-yl)methyl)(isopropyl)amino)cyclobutyl)propanoic acid (1.3 g, 2.1 mmol) and N,N-Diisopropylethylamine (1.20 mL, 6.90 mmol) and 4-(trifluoromethoxy)benzene-1,2-diamine (0.482 g, 2.51 mmol) in N,N-Dimethylformamide (13.0 mL, 167 mmol). The reaction was stirred overnight at RT and was partially concentrated to ca. 2 mls and then NaHCO3 (saturated) was added. The mixture was extracted with EtOAc (3×) and the combined organics were dried with MgSO4 filtered and concentrated. The residue was purified by flash chromatogrpahy (DCM/7N NH3 in MeOH 95:5) to the desired amide (1.4 g) as a solid.
