To a solution of 1,1-dimethylethyl cyclopropyl({2,3-dichloro-5-[(2E)-3-cyano-2-propen-1-yl]phenyl}methyl)carbamate (1 eq.) from the previous step in EtOAc (0.04 M) was added palladium (10% w/w over activated carbon, 0.1 eq). The vessel was evacuated and back filled with hydrogen. The reaction suspension was then stirred under a balloon atmosphere of hydrogen for 1.5 h. The reaction was quenched with dichloromethane and filtered through a bed of celite. The insolubles were washed further with EtOAc. Concentration of the filtrate in vacuo afforded the title compound as a colorless oil.
