To a suspension of (E)-4-chloro-2-fluoro-1-(2-nitroprop-1-enyl)benzene (5 g, 23.2 mmol) and ethyl 2-isocyanoacetate (2.65 mL, 24.4 mmol) in a mixture of dry THF (20 mL) and i-PrOH (20 mL) was added 2.6 mmol TBD/g polymer (9.8 g, 25.5 mmol). The suspension was stirred at room temperature for 5 d. The reaction mixture was filtered off and the residue was washed with i-PrOH/THF (1:1, 30 mL).
