[0248] 在队气氛下,将起始原料溶解于THF(0. 1M),并用冰浴将混合物冷却至0°C。然后, 将LiAlH4(2. Oeq.,在THF中浓度为2. 0M)逐滴加入到该溶液中并搅拌30分钟到1小时。
[0249] 在0°C下,非常缓慢地加入水(lmL/g的LiAlH4)并搅拌15分钟。然后,引入10% NaOH溶液(2mL/g的LiAlH4),并进一步搅拌15分钟。最后,加入过量的水(3mL/g的LiAlH 4)。 将产物通过cem#垫压过滤,并用EtOAc漂洗得到铝盐。然后,向滤液中加入过量的水,并且 将水相用EtOAc萃取三次。全部有机相干燥并减压蒸发,得到预期的酰胺基醚Ia(实施例 9-16),产物为无色油状物(产率:85-97% )。
