Reaction Steps

To a solution of 4-[5-(2-tolyl)-6-trifluoromethyl-pyridazin-3-yl]-piperazine-1-carboxylic acid tert-butyl ester (D11) (0.089 g, 0.21 mmol) in methanol (7 ml) was added Amberlyst® 15 ion exchange resin, acidic form (4.1 mmol/g) (0.257 g, 1.05 mmol) and the reaction mixture was shaken at room temperature for 18 h. After this period, the mixture was filtered and then a saturated solution of ammonia in methanol was added. The mixture was shaken for 1 h, filtered and the filtrate evaporated in vacuo. The residue was purified by HPLC and the desired fractions were collected and evaporated in vacuo to yield E8 (0.026 g, 50%) as a white solid. C16H17F3N4 requires 322; Found 323 (MH+).
