Reaction Steps
A mixture of Example 86a (0.136 g, 0.5 mmol) and cyclohexanamine (0.198 g, 2.0 mmol) in dioxane (2 mL) was heated under microwave conditions (140° C., 1 hour). The solvent was removed, and the residue was purified by flash chromatography (3:2 ethyl acetate/hexanes) on silica gel to give 0.164 g of the title product.
