Procedure

N,N,N′,N′-Tetramethyl-0-(7-azabenzotriazol-1-yl)uronium Hexafluorophosphate (0.84 g, 2.2 mmol) added to a solution 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)(ethyl)amino)cyclobutyl)propanoic acid (0.89 g, 1.5 mmol) and N,N-Diisopropylethylamine (0.84 ml, 4.8 mmol) and 4-tert-butylbenzene-1,2-diamine (0.29 g, 1.8 mmol) in N,N-Dimethylformamide (9 ml). The reaction was stirred overnight at RT, partially concentrated to ca. 2 ml 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 chromatography (DCM/7N NH3 in MeOH 94:6) to give the desired compound (0.88 g) as a colorless solid. Retention time C, 3.363 minutes.
