Reaction Steps
HBTU (2.06 g, 5.44 mmol) was added to a solution of diisopropyl ethylamine (1.03 mL, 5.93 mmol), o-phenylenediamine (0.54 g, 4.95 mmol), and 3-(benzyloxy)cyclobutanecarboxylic acid (1.02 g, 4.95 mmol) in DMF (20 mL) under argon atmosphere at 0° C. The mixture was stirred overnight with gradual warming to RT, then poured into water. The resulting suspension was filtered and the solid was air-dried to give N-(2-aminophenyl)-3-(benzyloxy)cyclobutanecarboxamide (1.17 g, 3.95 mmol, 80% yield) as an off-white solid.
