Morpholino-Ser(OBn) was prepared from N-Fmoc-Ser(OBn). Esterification of N-Fmoc-Ser(OBn) with isobutylene in the presence of a catalytic amount of H2SO4 afforded N-Fmoc-Ser(OBn)-OtBu. The Fmoc group was removed with piperidine in CH2Cl2 to produce Ser(OBn)-OtBu. Reaction of Ser(OBn)-OtBu with 4-morpholinecarbonyl chloride in pyridine yielded morpholino-Ser(OBn)-OtBu. Morpholino-Ser(OBn)-OtBu was hydrolyzed with TFA in CH2Cl2 to yield morpholine-Ser(OBn).
