Benzenesulfonyl chloride → (Tert-butyl)[(5-chloro(1,3-thiazol-2-yl))sulfonyl]amine

Participants

Reaction Steps

To a solution of (tert-butyl)(1,3-thiazol-2-ylsulfonyl)amine (0.15 g, 0.7 mmol) in ethyl ether (3 mL) at −78° C. was added a 1.6M solution of n-butyllithium (0.875 mL, 1.4 mmol) in hexanes via syringe under argon. The reaction mixture was stirred at −7,8° C. for 1 hr, then neat benzenesulfonyl chloride (90 μL, 0.7 mmol) was added. The resulting suspension was stirred at room temp for 2 hr. The reaction was diluted with EtOAc, washed with water and brine, dried, concentrated in vacuo and chromatographed (15% EtOAc/hexane) to give pure desired compound (58 mg, 33%). ES-MS (M+Na)+=277, 279 (Cl), (M-tBu+H)+=199, 201 (Cl).
