    摘要: The present invention provides an improved process for the preparation of Dolasetron salts, in particularly Dolasetron mesylate. Also provided are intermediates for the process and methods of preparing the intermediates. Intermediates for preparing Dolasetron according to the invention include 7-alkoxycarbonyl-9-(alkoxycarbonylmethyl)-3-trialkylsilyloxy-9-azabicyclo[3.3.1]nonane compounds (SAN compounds) and endo-9-alkoxycarbonyl-5-trialkylsilyloxy-8-azatricyclo[5.3.1.03,8]undecan-10-one compounds (SQO compounds).
