実験手順

To a mixture of compound 3l (900 mg, 2.7 mmol) and TEA (546 mg, 5.4 mmol) in acetonitrile (30 mL) was added 2-methoxybenzene sulfonyl chloride (559 mg, 2.7 mmol) and catalytic amount of DMAP. The reaction mixture was stirred at rt overnight. The solvent was evaporated in vacuo and purified by CC to give 3 as a white solid (510 mg, 38% yield).
