PROCEDURE
实验过程
Under N2 atmosphere, 1.0 g 4,N-diethyl-4,5-dihydro-pyrazole-1-carboxamidine was dissolved in 15 mL dry DCM, and 1.14 mL DiPEA and 1.31 g of 3-(chlorosulfonyl)benzoic acid were added. The mixture was stirred overnight at room temperature and evaporated to dryness. The residue was purified by flash chromatography (first column with DCM/MeOH/acetic acid 84:15:1; second column with DCM/MeOH/NH4OH 84:15:1) to yield 0.08 g (4%) of an off-white powder.
