Reaction Steps

The tert-butyl 2-[4-({6-[({[(1S,1aS,7bS)-4,7-difluoro-1,1a,2,7b-tetrahydrocyclopropa[c]chromen-1-yl]amino}carbonyl)amino]-3-pyridinyl}oxy)benzoyl]hydrazine carboxylate (49 mg, 0.089 mmol) in a mixture of dichloromethane (0.5 mL) and trifluoroacetic (0.5 mL) was stirred at room temperature for 30 min. The reaction was concentrated and purified on column chromatography (silica gel, 2% MeOH in CH2Cl2) to give the compound N-[(1S,1aS,7bS)-4,7-difluoro-1,1a,2,7b-tetrahydrocyclopropa[c]chromen-1-yl]-N′-{5-[4-(hydrazinocarbonyl)phenoxy]-2-pyridinyl}urea (17.6 mg, yield: 42%).
