Reaction Steps

To a 0° C. solution of amine from Step 1 above (200 mg, 0.4 mmol) in 6 mL of CH2Cl2 was added 0.28 mL (2.0 mmol) of Et3N followed by 0.11 mL (1.4 mmol) of methylsulfonyl chloride. The solution was stirred at 0° C. for 1.5 h, quenched with water and diluted with CH2Cl2. The organic layer was washed with brine, dried over MgSO4 and concentrated under reduced pressure. The residue was dissolved in 10 mL of a 1:1:1 mixture of THF:MeOH: 1 N K2CO3, stirred for 3.5 h at room temperature, quenched with a saturated aqueous NH4Cl solution and diluted with ethyl acetate. The organic layer was washed with brine, dried over MgSO4 and concentrated under reduced pressure. The residue was purified by flash chromatography on silica gel (100% ethyl acetate) to afford the methyl sulfonamide as a foam (114 mg, 51%).
