Reaction Steps

1-Chloro-2-iodo-4-nitro-benzene (2.00 g, 7.09 mmol) was dissolved in THF (30 mL) at 60° C. and EtOH (35 mL) was added followed by NH4Cl (0.569 g, 10.6 mmol in 30 mL of water) and iron powder (1.58 g, 28.4 mmol). This mixture was stirred vigorously for 3 h and then cooled in 22° C. and filtered though celite rinsing with EtOAc. The solution was then concentrated to 30 mL in vacuo and then poured into a 1:1 solution of 1N NaOH/brine (100 mL). This mixture was then extracted with EtOAc (3×50 mL) and the organics were dried over anhydrous MgSO4. Filtration and concentration gave compound 801B as a yellow solid. No purification was necessary. HPLC: 100% at 2.310 min (retention time) (YMC S5 ODS column 4.6×50 mm eluting with 10-90% aqueous methanol over 4 mincontaining 0.2% phosphoric acid, 4 mL/min, monitoring at 220 nm), MS (ES): m/z 517.6 [M+Na]+.
