Reaction Steps

(2S)-tert-butoxycarbonylamino-3-methylbutyric acid was attached to the resin as described for the preparation of compound 16 followed by reaction with (1R,2S)-1-amino-2-indanol as described for the preparation of 17 and removal of the Boc group as described for 18. The afforded compound was then reacted with the chlorocarbamate achieved from 12 as described for the preparation of 13 which, after purification by HPLC, gave the title compound (11 mg, 24% yield), Purity by HPLC >75% M+H+748.
