Reaction Steps

Utilizing the conditions of Hetz et. al., J.C.S. Perkin 1 1980, 306, to a solution of compound 39 (1 eq) in DMF is added triphenylphosphine (1 eq) and lithium azide (5 eq) at room temperature. Carbon tetrabromide (1 eq) is added and the reaction mixture is stirred until judged complete by tlc. MeOH is added to quench the reaction mixture and the solvent is evaporated under reduced pressure. The residue is purified by silica gel chromatography to yield the title compound, 40.
