Procedure: The starting material for this example, namely 5-[(1S,2S)-2-(benzyloxy)cyclohexyl]-1-(2-chlorophenyl)-2-(4-methoxyphenyl)-3-methyl-1,5,6,7-tetrahydro-4H-pyrrolo[3,2-c]pyridin-4-one, was prepared by following the methods described in Scheme 2 and Examples 12–19, using (1S,2S)-2-(benzyloxy)cyclohexylamine as R4NH2 (Scheme 2). Then, a sample of 5-[(1S,2S)-2-(benzyloxy)cyclohexyl]-1-(2-chlorophenyl)-2-(4-methoxyphenyl)-3-methyl-1,5,6,7-tetrahydro-4H-pyrrolo[3,2-c]pyridin-4-one (200 mg, 0.36 mmol) was dissolved in methylene chloride (5 mL). Trimethylsilyl iodide (0.054 mL, 0.396 mmol) was added dropwise and the solution was stirred at rt for 18 h. The solvent was removed and the crude material was purified by silica gel column, eluting with methylene chloride followed by methanol. The product was isolated as a white solid (40.0 mg, 24%). LC-MS m/z (MH+) 465.3, retention time 3.23 min (method 1). The solvent was removed the crude material was purified by silica gel column eluting with methylene chloride

Procedure: To a solution of 58.5 mg (0.15 mmol) of 1-carboxymethyl-5-(3-fluoro-5-trifluoromethyl-benzyloxy)-1H-pyrazole-3-carboxylic acid ethyl ester (3) in 5 mL of tetrahydrofuran was added 123 mg (0.60 mmol) of (1S, 2S)-2-benzyloxy-cyclohexylamine, 40 mg (0.30 mmol) of 1-hydroxybenzotriazole (HOBt) and 500 mg (0.60 mmol) of PS-carbodiimide resin, and the mixture was shaken at rt overnight. The reaction mixture was then treated with 200 mg (0.60 mmol) of MP-carbonate resin and 225 mg (0.9 mmol) of PS-TsOH resin, and shaken at rt for 4 h. The resulting mixture was filtered and washed with tetrahydrofuran (2×2 mL), and the combined tetrahydrofuran extracts were concentrated to afford crude 1-[((1S, 2S)-2-benzyloxy-cyclohexylcarbamoyl)-methyl]-5-(3-fluoro-5-trifluoromethyl-benzyloxy)-1H-pyrazole-3-carboxylic acid ethyl ester (4) which was used in the next reaction without any further purification. shaken at rt for 4 h The resulting mixture was filtered washed with tetrahydrofuran (2×2 mL) the combined tetrahydrofuran extracts were concentrated
