Procedure
A mixture of N-(3-amino-4-fluorobenzyl)-1-(trifluoromethyl)cyclopropanecarboxamide (3.17 g; 11.5 mmol) and TCDI (3.07 g; 17.2 mmol) in DCM (50 mL) was heated over night at 50° C. The mixture was concentrated and the residue purified by column chromatography to give the sub-title compound. Yield: 3 g (82%).
