A cleavage of N-tert-butyloxycarbonyl protection by Na2CO3 is reported. The N-free products are obtained in excellent yields. The compatibility of the method with the presence of acidic or basic groups is demonstrated. The reactions were performed on indole, azaindole, indazole, pyrazole, indolinone, quinolinone, and oxazolone. (c) 2006 Elsevier Ltd. All rights reserved.
