10 scheme 3 upon cleavage of 8h sub n 2 whereas only 7h tfa was obtained from the longer homolog 8h sub n 4 acid catalyzed cleavage of 3 methyl 2 butenoxymethyl resin to generate an allylic carbocation which is quenched by the thioether is a likely explanation for the formation 10 the lack of such a sulfonium impurity from 8h sub n 4 is likely the result of the cyclic ether formation discussed previously the use of a 3 m hcl solution that is prepared from acetyl chloride and dcm meoh 3 2 for cleavage eliminates the sulfonium byproduct affording 7h hcl upon evaporation schemes 4 and 5 depict the synthesis of a heteroaromatic and heterocyclic amine using the method of the present invention the starting resin bound tertiary alkyl carbamates in schemes 2 to 5 i e 8d 8h 8f and 13 are prepared using methodology similar to that disclosed in scheme 1 the following nonlimiting examples illustrate the inventors 39 preferred method for preparing compounds of the present invention str15 table 2______________________________________variables depending on the alkyl chain n removal conditions for thealkyl chain n linker fragments from 7d tfa______________________________________5 vacuum 2 5 mm hg 15 hours a fragment remains 4 vacuum 2 5 mm hg 15 hours 3 vacuum 2 5 mm hg 2 hours 2 not required______________________________________.
