Reaction Steps

Title compound was prepared from 2-(piperidin-4-yl)-1,2-dihydroisoquinolin-3(4H)-one hydrochloride in a manner analogous to the preparation of 4-Chloro-9-(2,2-dimethyl-propyl)-7-(S)-{2-oxo-2-[4-(2-oxo-1,4-dihydro-2H-quinazolin-3-yl)-piperidin-1-yl]-ethyl}-6,7,9,10-tetrahydro-3H-2,3,9-triaza-cyclohepta[e]inden-8-one. Material was obtained as yellow solid in 35% yield.
