Reaction Steps

A mixture of rpm161 (0.040 g, 0.114 mmol) 2-nitrophenylhydrazine (0.021 g, 0.126 mmol, 1.1 eq) and HCl (aq 4 M, 2 drops) in ethanol (3 mL) was heated in the CEM microwave at 120° C. for 15 min. After cooling to room temperature, pure product rpm168 was collected as an orange precipitate by filtration and dried in vacuo. The pure compound rpm168 was obtained without further purification (0.048 g, 0.099 mmol, 86%). MS (API-ES): m/z 459 (M+NH4)+; HRMS (API-ES) m/z Found: 459.1082 (M+NH4)+.
