1 6 different amines gave the desired amides l. 13 The title compounds Sa-at were obtained by the reaction of 6-chloro ribofuranuronamide 1 with different substituted (aminoethy1) indoles (method A) and then by the removal of the isopropylidene group in acidic medium, 1 N HC1 (method B) or HCOOH (50%)(method C), as outlined in Scheme 1. To obtain compounds 5a-c, l-substituted-3-(2-aminoethyl) indoles 7a-c were reacted directly on the ...
