Procedure: [(R)-1-(3-Methyl-butane-1-sulfonyl)-pyrrolidin-3-yl]-{3-[5-(2-trimethylsilanyl-ethoxymethyl)-5H-pyrrolo[2,3-b]pyrazin-2-yl]-pyridin-2-yl}-amine was prepared from (R)-pyrrolidin-3-yl-{3-[5-(2-trimethylsilanyl-ethoxymethyl)-5H-pyrrolo[2,3-b]pyrazin-2-yl]-pyridin-2-yl}-amine and 3-methyl-butane-1-sulfonyl chloride, following the general synthetic procedures described in the above Examples.

Conditions: temp:-78.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 2-(2,4-dichlorophenyl)-1-(4-hydroxyphenyl)-5-methyl-N-[5-(trifluoromethyl)pyridin-2-yl]-1H-imidazole-4-carboxamide, prepared as described in Ex. 13, Step 3 (139 mg, 0.27 mmol) and triethylamine (46 μl, 0.33 mmol) in dichloromethane (4.0 ml) were cooled to −78° C. 3-Methylbutane-1-sulfonyl chloride (56 mg, 0.33 mmol) was carefully added to the reaction mixture. The resulting mixture was stirred at −78° C. for 1 h, and then allowed to reach room temperature. Water was added to the reaction, and the phases were separated. The organic phase was washed with NaHCO3, brine and dried with Na2SO4. The solvent was removed under reduced pressure and separation by preparatory HPLC gave the title compound (81 mg, 46%) as a solid. to reach room temperature the phases were separated The organic phase was washed with NaHCO3, brine dried with Na2SO4 The solvent was removed under reduced pressure and separation by preparatory HPLC

Conditions: temp:0.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 2-(2,4-Dichlorophenyl)-1-(4-hydroxyphenyl)-5-methyl-N-piperidin-1-yl-1H-imidazole-4-carboxamide, prepared as described in Ex. 2, Step 1 (50 mg, 0.11 mmol) was dissolved in dichloromethane (3.0 ml), cooled to 0° C. and triethylamine (20 μl, 0.13 mmol) was added to the mixture. The resulting mixture was cooled to −78° C. and 3-methylbutane-1-sulfonyl chloride (23 mg, 0.13 mmol) was carefully added. The reaction was stirred at −78° C. for 1.5 h. Water was added to the reaction, the product extracted with dichloromethane and dried. The solvent was removed under reduced pressure and separation by preparatory HPLC gave the title compound (46 mg, 71%) as a solid. The resulting mixture was cooled to −78° C. the product extracted with dichloromethane dried The solvent was removed under reduced pressure and separation by preparatory HPLC
