Using hydroxide, tert-butyl ((1r,4r)-4-((8-(cyclopropyl(4-methoxybenzyl)amino)-3-((3-fluoropyridin-4-yl)carbamoyl)imidazo[1,2-b]pyridazin-6-yl)amino)cyclohexyl)carbamate to produce 6-(((1r,4r)-4-((tert-butoxycarbonyl)amino)cyclohexyl)amino)-8-(cyclopropyl(4-methoxybenzyl)amino)imidazo[1,2-b]pyridazine-3-carboxylic acid, please predict the condition, including solvent and agent in SMILES notation in json format like:

```JSON
{
    "solvent": [
        "CCN(CC)CC",
        "CCOC(C)=O"
