    • Typical Procedure For The Preparation Of Dimers: To A Solution Of Methyl 3achlorocarbonyloxy-7a12a-diacetoxy-5b-cholan-24-oate (569 Mg 1 Mmol) In THF (10 ML) Were Added 13-diaminobenzene (54.1 Mg 0.5 Mmol) And DMAP (122 Mg 1 Mmol) And The Mixture Was Stirred At Room Temperature Until All The Substrates Had Reacted (2 H). Addition Of H2O Followed By Extraction Of The Product With TolueneEt2O Gave The Crude Product Which Was Chromatographed On Silica Gel Column To Give Dimer 10 (528 Mg 90%) As A White Solid.36
