Procedure

(S)-tert-butyl 1-methyl-2-oxoazepan-3-ylcarbamate was prepared from (S)-tert-butyl 2-oxoazepan-3-ylcarbamate (Example 8) and methyl iodide according to the general procedure of Example 9. The crude product was purified by column chromatography, eluting with 50% ethyl acetate/hexanes, to provide compound (2e) in 48% yield.
