Reaction Steps

A solution of 3-(2-chloro-4-pyrimidinyl)-2-(4-fluorophenyl)-4,5,6,7-tetrahydro-7-methylpyrazolo[1,5-b]pyridazine (i.e. the product of Step B) (30.0 mg, 0.087 mmol) and cyclopropylamine (0.31 mL, 4.36 mmol) in 1-methyl-2-pyrrolidinone (2 mL) was heated under microwave irradiation at 150° C. for 30 minutes. The reaction mixture was diluted with water and extracted with ethyl acetate (3×10 mL). The combined organic layers were washed with brine, dried over magnesium sulfate, filtered and concentrated under reduced pressure. The crude residue was purified by medium pressure liquid chromatography using 20-80% ethyl acetate in hexanes as eluant to give 27 mg of the title product, a compound of the present invention, as a white solid.
