Participants

Reaction Steps

To a solution of formaldehyde (0.044 mL, 0.584 mmol) in methanol (2 mL) was added 1,1-dimethylethyl 2,2-dimethyl-1-piperazinecarboxylate (125 mg, 0.584 mmol, commercially available, for example from ChemPacific Corp., Baltimore, USA). The reaction mixture was stirred at room temperature for 1 hour before the addition of 4-(trifluoromethyl)phenylisocyanide (100 mg, 0.584 mmol, Fluorochem, Old Glossop, UK) and trimethylsilyl azide (0.092 mL, 0.701 mmol). The resulting reaction mixture was stirred at room overnight.
