To a 30 mL solution of 1:1 mixture of HNO3—H2SO4 was added benzothiazole (7.0 mL, 53 mmol) slowly over 1 h period at −25° C. and resulting solution was stirred for 12 h. Reaction temperature was allowed to warm up to 25° C. The reaction mixture was poured into ice water to produce a yellow precipitation which was subjected to column chromatography (CHCl3, neat) to yield 7.3 g (41 mmol, 79%) of the desired product.
