Participants

Reaction Steps

Dissolve 20.0 gm (0.03 mol) of the product from Step C in 30 ml DMF and treat with 7.5 gm (0.067 mol) KtBuO and 7.96 ml (0.067 mol) BnBr, with stirring for 18 hours. Evaporate the volatiles (0.5 mm and 45° C.) and take up the resulting residue in 1400 ml of EtOAc and water-wash (2×, 500 ml). The organic layer is then dried (MgSO4) and the solvent is evaporated (in vacuo). Flash chromatography on silica gel eluted with 20% EtOAc/hexane yields 12.4 gm (50%) of desired product as a clear viscous oil. Rf is 0.42 (silica gel plates eluted with 25% EtOAc/hexane).
