    摘要: The present invention relates to a novel process for preparing pyrrole ester compounds, which are key intermediates in the preparation of farnesyl transferase inhibitors, an anti-cancer agent Horner-Emmons reaction of aldehyde compounds provides the corresponding &agr;,&bgr;-unsaturated esters, which without any separation and/or purification steps, are treated with toluenesutfonyl-methylisocyanate in the presence of base to give pyrrole esters in one-pot fashion.
