Abstract: | An efficient synthesis of 13C6‐labeled Reyataz? (BMS‐232632) is described. 13C6‐labeled Reyataz? was synthesized in eight steps from commercially available [ring‐13C6]‐L ‐phenylalanine. The overall yield of the synthesis was 8% and the purity of the final product was greater than 98%. Copyright © 2005 John Wiley & Sons, Ltd. |
