実験手順

A suspension containing 7-(((5-bromo-4-chloro-2-nitrophenyl)amino)methyl)-3-neopentyl-1-oxa-3-azaspiro[4.5]decan-2-one (0.260 g, 0.532 mmol) and copper (I) cyanide (0.333 g, 3.72 mmol) in DMF (2 mL) was subject to microwave heating at 180° C. for 1.5 h. The reaction was cooled to rt, diluted with brine solution, and stirred for 20 min. The mixture was filtered through a pad of celite, and the celite was washed with EtOAc. The combined filtrates were washed with EtOAc. The combined organics were washed with water, dried over magnesium sulfate, filtered, and concentrated. The crude product was purified on a 24 g silica gel column (0-75% EtOAc/hexanes, 15 min gradient; 75% EtOAc/hexanes, 10 min; 35 mL/min elution; 254 nm detection) to afford the title compound as an orange solid. MS (m/z) 435.2 (M+H+).
