Procedure

Compound 38 (0.52 g, 1.1 mmol) and compound 12 (0.55 g, 1.1 mmol) were dissolved in DMF and HBTU (0.8 g, 2.1 mmol) was added as a solid followed by DIEA (0.52 ml, 3 mmol). The reaction mixture was stirred at room temperature overnight, diluted with EtOAc and the organic phase washed with saturated NaHCO3, brine, dried over MgSO4, filtered and concentrated to an oil. This oil was purified by flash silica chromatography (1 to 2 to 3 to 4 to 5% MeOH/CH2Cl2) to give a yellow foam (0.45 g, 0.47 mmol, 43%, compound 39).
