実験手順

N-(2-amino-4-chloro-5-(trifluoromethyl)phenyl)-3-(3-oxocyclobutyl)propanamide (72 mg, mmol) was taken up in acetic acid (3.2 mL) and the solution was heated at 65° C. for 26 h, upon which HPLC indicated the starting material was consumed and a new product had formed. The reaction mixture was cooled and the solvent was removed under high vac. The light brown residue was taken up in 20 mL ethyl acetate and the organic phase was washed with 10 mL portions of sat NaHCO3 and H2O. The organic phase was dried over Na2SO4, filtered and concentrated to yield a light brown glass. The crude material was purified by prep TLC (20 cm×20 cm×1.0 mm prep TLC plate, 3% MeOH/EA) to yield the title compound (45 mg, 66%) as a tan glass: MS (ESI+) for C14H12ClF3N2O m/z 317.2 (M+H)+; MS (ESI−) for C14H12ClF3N2O m/z 315.2 (M−H)−; HPLC purity 84.1% (ret. time, 2.98 min).
