实验步骤: Ethyl 4-amino-1-piperidinecarboxylate (300 mg) and triethylamine (258 mg) were dissolved in 5 ml of dichloromethane. To the mixture, 2 ml of solution of t-butylsulfinyl chloride (222 mg) in dichloromethane was added and the mixture was stirred at room temperature for 4 hours. The solution was partitioned into an aqueous solution of potassium hydrogen sulfate and ethyl acetate. The organic layer was washed with brine and dried over magnesium sulfate anhydride. The solvent was removed under reduced pressure and the residue was purified by silica gel chromatography to give 378 mg of 4-t-butylsulfinylamino-1-ethoxycarbonyl piperidine. The solution was partitioned into an aqueous solution of potassium hydrogen sulfate and ethyl acetate The organic layer was washed with brine dried over magnesium sulfate anhydride The solvent was removed under reduced pressure the residue was purified by silica gel chromatography

实验步骤: Intermediate 2 (0.05 mmol) was dissolved in THF (1.0 mL). Triethylamine (0.12 mmol) and 2-methylpropane-2-sulfinyl chloride (0.06 mmol) was added. The reaction mixture was left at rt for 16 hours. The pure compounds were obtained by standard preparative HPLC purification of the reaction mixture.

实验步骤: To a solution of 9-(3-aminopropyl)-2-fluoro-8-((6-iodobenzo[d][1,3]dioxol-5-yl)methyl)-9H-purin-6-amine (80 mg, 0.17 mmol) in DCM (3 mL) was added t-butylsulfinyl chloride (28 uL, 0.25 mmol) and triethylamine (30 uL, 0.25 mmol). The resulting mixture was stirred at room temperature overnight. The reaction mixture was condensed and purified by flash chromatography to yield WS60 as a white solid (45 mg, 46%). 1H NMR (500 MHz, CDCl3): δ 7.28 (s, 1H), 6.62 (s, 1H), 6.04 (brs, 2H), 5.97 (s, 2H), 4.60 (t, J=6.5 Hz, 1H), 4.24 (s, 2H), 4.20 (m, 1H), 4.09 (m, 1H), 3.13 (m, 1H), 2.97 (m, 1H), 2.00 (m, 1H), 1.85 (m, 1H), 1.27 (s, 9H).

实验步骤: To a solution of 2-bromoethaneamomium bromide (410 mg, 2 mmol) in 20 mL of CH2Cl2 was added triethylamine (3697 μL, 5 mmol). The resulting mixture was stirred at a temperature of about 25° C. for 30 min, then cooled down at 0° C. 2-methylpropane-2-sulfinic chloride (0.73 mL, 2.2 mmol) was added dropwise, kept stirring for 1 hr and allowed to warm up to a temperature of about 25° C. and stirred for about 16 hours. The resulting mixture was condensed and purified by flash chromatography to provide 2-methyl-propane-2-sulfinic acid (2-bromo-ethyl)-amide as a white solid (0.42 g, 86% yield). cooled down at 0° C kept stirring for 1 hr to warm up to a temperature of about 25° C. stirred for about 16 hours condensed purified by flash chromatography
