Procedure
(R)-2-[2-Amino-2-(3-methyl-1,2,4-oxadiazol-5-yl)-ethylsulfanyl-methyl]-3-[dimethyl-(1,1,2-trimethyl-propyl)-silanyloxy]-5-methoxy-6-methyl-benzoic acid methyl ester was treated with ammonium fluoride in methanol in an analogous manner to the procedure described in Example 1 to yield (R)-2-[2-amino-2-(3-methyl-1,2,4-oxadiazol-5-yl)-ethylsulfanyl-methyl]-3-hydroxy-5-methoxy-6-methyl-benzoic acid methyl ester as an amorphous foam.
