Steps:

1.b EXAMPLE 1b

EXAMPLE 1b To prepare 4-(benzyloxy)3-chloronitrobenzene, benzyl alcohol (0.34 kg, 3.14 mole, 1.10 eq) was dissolved in acetonitrile (1.70 L) and to it was added potassium hydroxide flakes (85%) (0.24 kg, 1.50 eq). The resulting suspension was warmed to 25° C. A solution of the 3-chloro-4-fluoronitrobenzene (0.50 kg, 2.85 mol, 1.0 eq) in acetonitrile (0.75 L) was added keeping the pot temperature<45° C. The mixture was held for 14 h. The mixture was then cooled back to 0-15° C., quenched with water (2.5 L) and the resulting slurry was filtered and washed with water (2*0.50 L).
