Procedure

A solution of (S)-tert-Butoxycarbonylamino-(1-methyl-cyclohexyl)-acetic acid (0.217 g; 0.80 mmol) (prepared according to Tetrahedron Let. 2007, 48, 6343-6347) and HATU (0.38 g; 1.00 mmol) in DCM (10 mL) was stirred for 20 min at ambient temperature. After addition of DIPEA (0.698 mL; 4.00 mmol) and (5R,8S)-7-((S)-2-Amino-3,3-dimethyl-butyryl)-10,10-dimethyl-7-aza-dispiro[3.0.4.1]decane-8-carboxylic acid [(1R,2S)-1-(pyrrolidine-1-sulfonylaminocarbonyl)-2-vinyl-cyclopropyl]-amide (0.400 g; 0.67 mmol) in DCM (10 mL) the reaction mixture was stirred for 15 h, the solvent was removed in vacuo and the residue was purified by preparative HPLC (method L) to yield the title compound. LC-MS (method E): Rt=2.91 min; M/z=818 [M+H], HPLC (method A3) Rt=7.18 min
