Reaction Steps
In a manner similar to that described in Scheme 1 (Step 3), 6-chloro-3-iodo-1-trityl-1H-pyrazolo[4,3-c]pyridine (3a) was coupled with isopropenylboronic acid pinacol ester to provide 6-chloro-3-(prop-1-en-2-yl)-1-trityl-1H-pyrazolo[4,3-c]pyridine. MS ESI calc'd. for C28H22ClIN3 [M+1]+ 436, found 436.
