Procedure: Reaction of 2-biphenylyl isothiocyanate (9.1 g) in ethanol (25 ml) with 25% aqueous ammonia solution (50 ml) at ambient temperature for 18 hours gave N-(2-biphenylyl)thiourea (m.p. 187°-188° C.).

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Reaction of 2-aminobiphenyl (10 g) with thiophosgene (10.2 g) in a mixture of dioxane (15 ml) and water (50 ml) at 0°-5° C. for 30 minutes and at ambient temperature for 2 hours with stirring gave 2-biphenylylisothiocyanate as a yellow oil.

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Treatment of 2-biphenylylisothiocyanate (10.2 g) with a saturated solution of ammonia in ethanol (100 ml) at 10 to 30° for 4 hours and then at 30° C. for 16 hours yielded N-(2-biphenylyl)thiourea (m.p. 183°-184° C.).

Conditions: temp:30.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of 2-aminobiphenyl (10.2 g), thiophosgene (10.4 g), dioxane (50 ml) and water (100 ml) was prepared with cooling in an ice bath. The temperature was raised to 30° C. and stirred for 3 hours at 30° C. to yield 2-biphenylylisothiocyanate as a yellow oil. was prepared with cooling in an ice bath
