4-Toluenesulfonyl chloride → HCID 86662381, compound

Participants

Reaction Steps

To a solution of tert-butyl [3-hydroxy-1-(3-nitrophenyl)propyl]carbamate (4.00 g; 13.50 mmol; 1.00 eq.) in anhydrous DCM (15 mL) and N,N-diethylethanamine (2.82 ml; 20.25 mmol; 1.50 eq.) at 0° C. was added dropwise 4-methylbenzenesulfonyl chloride (3.09 g; 16.20 mmol; 1.20 eq.). The mixture was stirred at room temperature for 15 h. After workup, the crude product was purified by flash chromatography on silica gel (EtOAc:Hex from 10:90 to 20:80) to provide 5.5 g of the 3-[(tert-butoxycarbonyl)amino]-3-(3-nitrophenyl)propyl 4-methylbenzenesulfonate.
