Reaction Steps

The reaction was carried out using the procedure described in Example 1, Step 4, using 3-isoxazol-3-yl-6-(2,2,2-trifluoroethoxy)-[1,2,4]triazolo[3,4-α]phthalazine (WO-A-9850385) (100 mg, 0.29 mmol) instead of 6-chloro-3-(5-methylisoxazol-3-yl)-[1,2,4]triazolo[3,4-α]phthalazine with [2-(2-dimethylaminoethyl)-2H-[1,2,4]triazol-3-yl]methanol (Example 4, Step 2) (51 mg, 0.29 mmol). Crude residue was purified on silica eluting 2-6% MeOH/DCM, followed by crashing out from DCM using isohexane. The title compound was isolated by filtration to give a cream solid (47 mg, 39%).
