Participants

Reaction Steps

A mixture of 5-(4-bromo-5-chloropyrimidin-2-yl)thiophene-2-sulfonyl chloride (164 mg, 0.45 mmol, 1.0 equiv.), tert-butyl hydrazinecarboxylate (119 mg, 0.9 mmol, 2.0 equiv.) and DIPEA (5 mL) was stirred in DCM at r.t. for 2 h, The reaction was extracted with EA and the combined layers were dried (Na2SO4), filtered. The filtrate was concentrated to afford tert-butyl 2-(5-(4-bromo-5-chloropyrimidin-2-yl)thiophen-2-ylsulfonyl)hydrazinecarboxylate (179 mg, 85%). LC-MS (m/z)=469 [M+H]+
