Reaction Steps

To a solution of methyl 2-[(R)-4-(6-benzyl-4,5-dimethyl-pyridazin-3-yl)-2-methyl-piperazin-1-yl]-4-trifluoromethyl-pyrimidine-5-carboxylate (500 mg, 1.0 mmol, 1.0 eq) in THF (5 mL) is added an aqueous solution of LiOH (1 M, 2.0 mL, 2.0 mmol, 2.0 eq) and the resulting solution is heated to 75° C. for 4 h. The reaction mixture is diluted with EtOAc (50 mL) and washed with water (3×15 mL). The combined aqueous washes were adjusted to pH 6 with aqueous HCl (1 M), then extracted with dichloromethane (3×50 mL). The combined organic layers are dried over sodium sulfate and concentrated under reduced pressure to yield the desired product as a white solid (470 mg, 96%).
