実験手順

A solution of 0.26 g (1.21 mmol) of (±)-cis-6-(2-aminoethyl)-2,2-dimethyl-1,3-dioxane-4-acetic acid and 0.504 g (1.20 mmol) of (±)4-fluoro-α-[2-methyl-1-oxopropyl]-γ-oxo-N,β-diphenylbenzenebutaneamide mixture of [R-(R*,R*)], [R-(R*,S*)], [S-(R*,R*)] and [S-(R*,S*)] isomers in 5 mL of dimethyl sulfoxide is heated at 105° C. for 15 hours. The solution is cooled and poured into 100 mL of diethyl ether and 50 mL of saturated ammonium chloride in water. The layers are separated and the organic layer washed with water (2×50 mL) and 5% sodium hydroxide solution (2×100 mL--to extract the intermediate from unreacted diketone). The aqueous layer is acidified with dilute hydrochloric acid solution and extracted with 30 mL of ethyl acetate. A drop of concentrated hydrochloric acid is added to the ethyl acetate solution and allowed to stand 18 hours. The solution is concentrated in vacuo and the concentrate is redissolved in 30 mL of ethyl acetate treated with one drop of concentrated hydrochloride acid. The solution is stirred two hours, concentrated in vacuo, and dissolved in 6 mL of toluene. Trans-(±)-5 -(4-fluorophenyl)-2-(1-methylethyl)-N,4-diphenyl-1-[2-(tetrahydro-4-hydroxy-6-oxo-2 H-pyran-2-yl)ethyl]-1 H-pyrrole-3-carboxamide crystallizes and is isolated by filtration. A total of 0.16 g of trans-(±)-5-(4-fluorophenyl)-2-(1-methylethyl)-N,4-diphenyl-1-[2-(tetrahydro-4-hydroxy-6-oxo-2 H-pyran-2-yl)ethyl]-1 H-pyrrole-3-carboxamide is isolated in two crops.
