Reaction Steps

(4R-cis)-1-[2-[6-[2-(diphenylamino)-2-oxoethyl]-2,2-dimethyl-1,3-dioxan-4-yl]ethyl]-5-(4-fluorophenyl)-2-(1-methylethyl)-N,4-diphenyl-1H-pyrrole-3-carboxamide is dissolved in methanol (300 mL) and reacted by adding 1.0 N hydrochloric acid (100 mL) and stirring for 12 hours at room temperature. The white crystalline solid [R-(R*,R*)]-5-(4-fluorophenyl)-β,δ-dihydroxy-2-(1-methylethyl)-N,N,4-triphenyl-3-[(phenylamino)carbonyl]-1H-pyrrole-1-heptanamide is isolated by filtration (mp 228.5°-232.9° C., uncorrected).
