Procedure
A mixture of the crude 2,3-difluoro-6-iodo-4-methylphenyl isocyanate from D20, 4-amino-1-N-Boc piperidine (480 mg), and dichloromethane (5 ml) was stirred at room temperature for 18 h then evaporated and directly purified by chromatography on silica gel 20 g eluting with 10-50% ethyl acetate in hexane to give the title compound, 300 mg. M−−H=494.
