Participants

Reaction Steps

Combine 2-amino-5-isopropyl-benzonitrile (3.19 g, 20 mmol), 1-fluoro-2-nitro benzene (2.1 mL, 20 mmol) and lithium hydroxide (1.68 g, 40 mmol) in DMSO (40.0 mL) and heat at 55° C. for 19 hours. Cool to ambient temperature and dilute with water (200 mL). The title compound precipitates as 4.56 g of an orange solid: mp 91–96° C.; mass spectrum (ion spray) m/z=280 (M+1).
