N-(3-bromopropyl)methanesulfonamide

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a cooled solution of 2-bromopropylamine hydrobromide (43.8 g., 0.20 mole) in pyridine (100 ml.) was added over a period of 40 minutes methanesulfonyl chloride (15.2 ml., 0.20 mole). The reaction mixture was stirred for 15 minutes and then diluted with ether. The remaining solid was filtered off, washed with about 200 ml. of acetone. The filtrate and washes were concentrated in vacuo. The residue was extracted with three 100 ml. portions of acetone. Upon evaporation of the acetone, 30.4 g. of a thick oil representing the title compound. The product was confirmed by infrared analysis and nuclear magnetic resonance. The remaining solid was filtered off washed with about 200 ml The filtrate and washes were concentrated in vacuo The residue was extracted with three 100 ml Upon evaporation of the acetone, 30.4 g

実験手順: To a solution of 8-((6-iodobenzo[d][1,3]dioxol-5-yl)thio)-9H-purin-6-amine (150 mg, 0.36 mmol) in 10 mL of dry DMF was added N-(3-bromopropyl)methanesulfonamide (300 mg, 1.4 mmol) and Cs2CO3 (190 mg, 0.58 mmol). The resulting mixture was stirred at a temperature of about 25° C. for 3 hrs, condensed under reduced pressure and purified by flash chromatography to provide compound WS34 as white solid (49 mg, 25% yield). condensed under reduced pressure purified by flash chromatography
