Reaction Steps

A sample of 5-Amino-indan-1-one (100 mg, 0.68 mmol) is treated with a solution pyridine (59 mg, 0.75 mmol) in a mixture of dichloromethane (1.5 mL) and tetrahydrofuran (1.5 mL). The reaction is then cooled in an ice bath. A solution of methanesulfonyl chloride (86 mg, 0.75 mmol) in tetrahydrofuran (1.5 mL) is added dropwise and the reaction is allowed to stir for 2 hours at ice bath temperature and overnight at room temperature. The reaction is diluted with ethyl acetate and extracted twice with 1 M HCl. The organics are dried over MgSO4 and the solvent is removed to afford the title material (64 mg, 42% yield) which is not purified but carried on as is: LC/MS calculated for [M+H]+ C10H11NO3S: 226.0, found: 226.0.
