The present invention relates to compounds of formula (I) : and pharmaceutically acceptable salts thereof, wherein R1and R2 are various ring systems. The invention also relates to pharmaceutical compositions comprising these compounds, methods of using these compounds in the treatment of Rho Kinase mediated diseases and disorders, processes for preparing these compounds and intermediates useful in these processes.
3-(o-Trifluoroacetamidoaryl)-1-propargylic esters: common intermediates for the palladium-catalyzed synthesis of 2-aminomethyl-, 2-vinylic, and 2-alkylindoles
3-(o-Trifluoroacetamidoaryl)-1-propargylic esters have been used as common synthetic intermediates for the preparation of a variety of 3-unsubstituted 2-substituted indoles. Treating ethyl 3-(o-trifluoroacetamidoaryl)-1-propargylic carbonates unsubstituted or containing an aryl substituent at the propargylic carbon with piperazines and Pd(PPh3)4 in THF at 80 °C affords 2-(piperazin-1-ylmethyl)indoles in excellent yields
