Ammonia → HCID 21882742, compound

Participants

Reaction Steps

2.02 g of 2-fluoro-4-(2-phenylethoxy)-3-nitropyridine (starting material K3) are dissolved in 10 ml of a 5M solution of ammonia in methanol and stirred at ambient temperature for 16 hours. The solvent is distilled off and the residue is chromatographed on silica gel (dichloromethane/petroleum ether 4:1+1% triethylamine). Concentration of the pure fractions and drying in vacuo gives 1.16 g of the title compound as a yellow solid of m.p. 131–132° C. The mass spectrum shows the molecular peak MH+ at 260.0 Da.
