Reaction Steps

1-Chloro-4-fluoro-2-methyl-5-nitrobenzene (D22) (1.5 mmol, 284 mg) in dimethylformamide (5 mL) was treated under argon at room temperature with 1,1-dimethylethyl 4-amino-1-piperidinecarboxylate (1.5 mmol, 300.5 mg, 1 eq) and diisopropylethylamine (1.5 mmol, 194 mg, 1 eq) then stirred at 75° C. overnight. The mixture was concentrated under reduced pressure, treated with 10% Na2CO3 aqueous solution and extracted twice with ether. Organics were combined, dried on MgSO4 and concentrated under reduced pressure to give the title compound as a clean orange solid (1.46 mmol, 539 mg, 97% yield). M−H=368.16.
