A solution of 2-[(5S)-3-(6-bromopyridin-3-yl)-2-oxo-5-(propan-2-yl)imidazolidin-1-yl]-N-[3-(trifluoromethyl)phenyl]acetamide (150 mg), zinc cyanide (91 mg), Pd2(dba)3 (8.5 mg), Xantphos (11 mg), and N,N,N′,N′-tetramethylethylenediamine (14 μL) in DMF (2 mL) was stirred under irradiation with microwave at 180° C. for 30 min. Additional zinc cyanide (91 mg) was added thereto, and the resulting mixture was stirred under the same condition for 30 min. NH silica gel was added thereto, the mixture was stirred, followed by filtration, and the filtrate was concentrated under reduced pressure. The residue was purified by preparative HPLC to afford the title compound (47 mg).
