Reaction Steps
Methanesulfonyl chloride (371 μL, 4.79 mmol) was added to a solution of the aniline of Example 103 (725 mg, 2.4 mmol) and Et3N (1 mL, 7.17 mmol) in DCM (10 mL) at 0° C. After stirring at 0° C. for 1 h the reaction was allowed to warm to room temperature before the solvent was removed in vacuo. 2M NaOH (10 mL) was added to the residue and the mixture was stirred overnight. The resulting clear solution was neutralised by the addition of sat aq NH4Cl and extracted with DCM (2×30 mL). The combined organic layers were dried (MgSO4) and evaporated to give an oil. This was taken up in EtOAc (10 mL), the HCl salt was precipitated by the addition of 1M ethereal HCl and the product (669 mg, 67%) was collected by filtration; δH (d6-DMSO, 400 MHz) 2.23 (3H, s), 2.42 (3H, s), 2.75 (6H, s), 3.04 (3H, s), 4.38 (2H, s), 6.84 (1H, d), 6.93 (1H, d), 6.98 (1H, s), 7.17-7.25 (2H, m), 7.50 (1H, s); MS m/z (ES+) 381 (MH+).
