Participants

Reaction Steps

The title compound was prepared from N-(5-amino-2-nitro-phenyl)-acetamide [prepared from commercially available 5-chloro-2-nitroaniline as described in Example F6] and 2,5-dimethoxy-3-methoxymethyl-tetrahydro-furan [prepared from (2,5-dimethoxy-tetrahydro-furan-3-yl)-methanol [CAS-no. 207119-66-2] by methylation with 2.1 eq. NaH (95%) and 5.5 eq. Mel in Et2O at 0° C. for 2 h] in HOAc at 60° C. for 18 h according to the general procedure F. Obtained as a light yellow solid (86 mg). Deacetylation of this material was perfomed by stirring with 2 eq. 2 N NaOH-sol. in 1,4-dioxane at 60° C. for 2 h. Obtained as a yellow solid (69 mg).
