1-((4-methoxyphenyl)methyl)-1H-pyrazol-4-amine → 2-[5-[1-(4-Methoxy-benzyl)-1H-pyrazol-4-ylcarbamoyl]-2-oxo-1-(2-trimethylsilanyl-ethoxymethyl)-1,2-dihydro-pyridin-3-yl]-indole-1-carboxylic acid tert-butyl ester

Reaction Steps

The title compound was prepared according to the experimental used in Example 1, Step 4 using intermediate (1c) and 1-(4-methoxy-benzyl)-1H-pyrazol-4-ylamine. After the usual aqueous work up, the resultant crude product was purified by flash chromatography on SiO2 eluting with hexane—50% ethyl acetate/hexane. This afforded the title compound as a pink solid, 180 mg, 50%.
