Reaction Conditions

Reaction Steps

A mixture of crude tert-butyl (1-{4-[bromo(phenyl)acetyl]phenyl}cyclobutyl)carbamate [that was prepared in a manner analgous to that described for Intermediate Example Int-1-A] (391 mg, ˜80% purity, 0.710 mmol, 1.0 eq), 6-methoxy-4,5-dimethylpyridazin-3-amine (that was prepared in a manner analgous to that described for Intermediate Example Int-34, Step 1, 108 mg, 0.710 mmol, 1.0 eq) and N,N-diisopropylethylamine (140 μL, 0.780 mmol, 1.1 eq) in butyronitrile (4.9 mL) was heated for 3 hours at 120° C. On cooling the reaction mixture was concentrated in vacuo. The crude mixture was purified via MPLC (Biotage Isolera; 25 g SNAP cartridge: hexane/EtOAc 9/1→hexane/EtOAc 2/3) to give 105 mg (28% yield) of the title compound.
