该中间体在本合成路线中的序号：(IV)The condensation of indeno[1,2-d]oxazole derivative (I) with (S)-(+)-glycidyl tosylate (II) by means of LiHMDS gives the adduct (III), which is deprotected with HCl to yield the epoxide (IV). Finally, this compound is condensed with the dibenzylpyrrolidone (V) by means of P4 phosphazene base (commercially available) in THF to afford the target amide.
