실험 절차

The procedure of Referential Example 16 was repeated, except that 3-bromophenyl isothiocyanate (25.0 g) serving as a starting material was used, to thereby yield N-(3-bromophenyl)thiourea (19.4 g) as colorless crystals. Subsequently, The procedure of Referential Example 17 was repeated, to thereby yield 2-amino-5-bromobenzothiazole (1.21 g). Thereafter, The procedure of Referential Example 18 was repeated, to thereby yield the title compound (227 mg).
