YieldReaction ConditionsOperation in experiment
65% Step 1 Variation A (S)-3-amino-piperidine-1-carboxylic acid tert-butyl ester (0.1 g, 0.378 mmol) was dissolved in DCM (3 mL). N,N-diisopropylethylamine (0.23 mL, 1.324 mmol) was added and the resulting light yellow solution was cooled by a NaCl/ice bath. After about 20 minutes phosgene 20% in toluene (0.24 mL, 0.454 mmol) was added. After about 20 minutes (1R,2S)-2-methyl-cyclohexylamine hydrochloride (0.068 g, 0.454 mmol) was added. The resulting mixture was stirred in the NaCl/ice bath for an hour. 1 mL of MeOH was added and the mixture was allowed to warm up to RT before being evaporated. The remaining oil was partitioned between DCM and H2O. The aqueous layer was extracted twice with DCM, the organic layers were combined, dried over Na2SO4, filtered and evaporated. The residue was purified by SiO2 chromatography (24 g SiO2, DCM/(DCM:MeOH:NH4OH 60:10:1) 100 to 83% DCM) to give 0.1 g of 1-((1R,2S)-2-methyl-cyclohexyl)-3-[5-(2-trimethylsilanyl-ethoxymethyl)-5H-pyrrolo[2,3-b]pyrazin-2-yl]-urea as a light brown solid (65% yield).

YieldReaction ConditionsOperation in experiment
16% Step 2: To cis (2-methyl-cyclohexyl)-((R)-1-phenyl-ethyl)-amine (0.65 g, 2.99 mmol) Pd(OH)2 on carbon 20 wt % (0.3 g) and EtOH (10 mL) were added and the reaction mixture stirred at RT under 1 atm of H2 overnight. The palladium was filtered off and the solvent was evaporated (be careful, the free amine sublimes). The remaining material was purified by SiO2 chromatography (40 g SiO2, DCM/(DCM:MeOH:NH4OH 60:10:1) 100-71% DCM). TLC shows only one major spot. Ten fractions were evaporated at a time. After running NMR the first 20 were combined and evaporated. The residue was dissolved in DCM and treated with 4M HCl in dioxane. The solvent was evaporated and the remaining solid was dried under high vacuum to give 0.075 g of (1R,2S)-2-methyl-cyclohexylamine hydrochloride as an off-white solid (16% yield). NMR showed the presence of about 5% of the trans isomer.
