The core of this compound is the ring system of pyrazolo [3,4-c] pyridine. At position 1, there is a 4-methoxybenzyl group connected. This 4-methoxybenzyl group is above the benzyl group, and is connected to a methoxy group in the para-position. At position 6, there is a 4-fluorobenzyl group, that is, the para-position of the benzyl group is substituted by a fluorine atom. At position 7, there is a monooxy group, that is, there is a carbonyl group.
At position 3 of the ring system, there is a group of ethyl carboxylate. This ethyl carboxylate is formed by esterification of the carboxyl group with ethanol.
As for the 4,5,6,7-tetrahydro, it means that the double bonds of the 4,5,6,7 positions of the pyrazolo [3,4-c] pyridine ring system are all converted into single bonds by hydrogenation reaction, and four hydrogen atoms are introduced. < Br >
