Reaction Steps

1-(4,9-Dimethoxynaphtho[1,2-b:5,6-b′]dithiophen-2-yl)dodecan-1-one (0.70 g, 1.45 mmol), KOH (1.80 g, 32 mmol), and hydrazine monohydride (1.8 mL, 38 mmol) were heated in 2,2′-oxydiethanol (15 mL) at 200° C. under nitrogen overnight. After the mixture was cooled to room temperature, dichloromethane (100 mL) was added and washed with water (4×50 mL). Dried with Na2SO4, and after solvent was removed, 2-dodecyl-4,9-dimethoxynaphtho[1,2-b:5,6-b′]dithiophene was obtained.
