Procedure

The compound obtained in step (a) (0.2 g, 0.53 mmol) was dissolved in 1,4-dioxane (5 ml), HBTU (0.19 g, 0.5 mmol) and DIEA (0.32 g, 2.5 mmol). The mixture was stirred for 10 minutes and aminoacetonitrile hydrochloride (0.55 g, 0.6 mmol) was added. After 1 h the mixture was evaporated and the residue purified by chromatography on silica to give the amide (0.15 g, 72%) as a white solid.
