Reaction Steps
The procedure described in Example 3: step b was followed using 2-bromo-3-methyl-phenylamine (185 mg, 1.0 mmol, Example 25: step a), PdCl2(PPh3)2 (70.2 mg, 0.1 mmol), dioxane (3 mL), and Et3N (729 μL, 6 mmol), 4,4,5,5,-tetramethyl-[1,3,2]-dioxaborolane (453 μL, 3 mmol). Purification by preparative SiO2 TLC (25% EtOAc in hexanes) of the residue yielded the title compound (94 mg, 40%) as a yellow solid. ESI-MS (m/z): Calcd. for C13H20BNO2: 234.1 (M+H) found: 234.1.
