Abstract
Primary amines are diprotected as their 2, 5-bis [(triisopropylsilyl) oxy] pyrrole derivatives (BIPSOP). This protecting group is stable to strong bases such as organolithiums and alkoxides at 0° C and to temperatures up to about 150° C. Removal may be accomplished by a mild two step sequence.
