Conditions

Temperature

Procedure

500 mg 2(2-Cyano-3,5-difluoro-phenyl)-(2-fluoro-4-iodo-phenyl)-carbamic acid tert-butyl ester (1.05 mmol, 1 eq.) and 412 mg Cs2CO3 (1.27 mmol, 1.2 eq) were dissolved in 5.5 mL DMF and treated with 265 mg (3-hydroxy-phenyl)-carbamic acid tert-butyl ester (1.27 mmol. 1.2 eq.) dissolved in 5.5 mL DMF. The resulting mixture is stirred at 50° C. for 16 h. Extractive workup provided a crude product containing the desired target compound as a mixture of regioisomers along with a smaller fraction of the product of double substitution. This mixture was advanced without further purification.
