A solution of 150 mg (0.19 mmol) of a 1:1 mixture of (2S,4R)-1-(Naphthalene-2-sulfonyl)-4-tritylsulfanyl-pyrrolidine-2-carboxylic acid [1-(4-methoxy-benzyl)-1H- and [2-(4-methoxy-benzyl)-2H-tetrazol-5-ylmethyl]-methyl-amide in 10 ml TFA was treated with 0.3 ml (1.9 mmol) triethylsilane, refluxed for 7 min at 80° C. and evaporated. Crystallization from CH2Cl2/Et2O gave 46 mg (57%) (2S,4R)-4-Mercapto-1-(naphthalene-2-sulfonyl)-pyrrolidine-2-carboxylic acid methyl-(1H-tetrazol-5-ylmethyl)-amide, mp: 175 slow dec., MS: 433 (MH+).
