A solution of 2-hydroxydibenzofuran (1.47 g, 7.98 mmol), butyl isocyanate (1.26 mL, 11.2 mmol) and triethylamine (0.89 mL, 6.39 mmol) in 50 mL of methylene chloride was stirred under N2 at room temperature for 1 hour. The solvent was removed under reduced pressure to give a solid. Recrystallization from diethyl etherhexane gave 1.23 g (54%) of the title compound as a white crystalline solid, mp 124°-126° C.
