Participants

Reaction Steps

To a solution of 0.748 g (4.48 mmol) of the product of Example 30 in 10.0 mL of pyridine was added 0.928 g (4.48 mmol) of p-methoxybenzenesulfonyl chloride. The reaction mixture was stirred for 24 h at room temperature and then diluted with chloroform and washed with 5% HCl solution and water. The organic layer was then dried over MgSO4, filtered and concentrated in vacuo. The residue was triturated with ether-hexanes and the resulting solid was filtered and dried to provide 0.86 g (57%) of the desired product as a tan solid. Electrospray Mass Spec: 338.2 (M+H)+
