Procedure

To a solution of 0.886 g of CIS-(+/-)-2-Butyl-6-(hexahydropyrrolo[1,2-b]isoxazol-2-yl)-3-[[2'-[1-(triphenylmethyl)-1H-tetrazol-5-yl][1,1'-biphenyl]-4-yl]methyl]-4(3H)-quinazolinone dissolved in 2.0 ml of tetrahydrofuran is added 10.0 ml of methanol. The reaction mixture is heated at reflux for 18 hours, cooled and concentrated in vacuo to a residue which is purified by chromatography on silica gel using 9:1 chloroform-methanol to give 0.534 g of the desired product as a white foam. FAB mass spec 548 (M+H).
