This is incorrect. The scriptPubkey is not the private key. The scriptPubKey is the hex of the output script that you are spending from. You are also missing the parameter for the private key array that goes right before the sighash parameter. Even if you don't need that parameter (i.e the key is in your wallet), you still need to specify it if you are going to have the sighash parameter as well.

If the transaction you are spending from is in your wallet, you do not need anything except the hex of the unsigned transaction. The rest will be automatically filled in for you.

Also, protip. Use a single quote to wrap all the JSON stuff and you won't need to escape the double quotes since they are all read as literals.

redeemScript should be blank. Also, you need the amount field, I forgot about that.

Something's wrong with your command. I need to look a bit into it some more.

Edit: I found the problem. The scriptPubKey is the scriptPubKey of the output that you are spending from, not the one you are spending to. It should be 76a90ddfd0dee20dbe590f70298817810acc0c3c955888ac
