Sodium hydride, 60% dispersion in mineral oil (0.13 g, 3.18 mmol) was added to a solution of cis-3-(benzo[d]thiazol-2-ylamino)cyclobutanol hydrochloride (0.20 g, 0.795 mmol) in N,N-dimethylformamide (2.7 mL) under argon and the mixture was stirred for 30 min at RT. 1-(4-(2-Fluoropyridin-3-yl)-5,6-dihydropyridin-1(2H)-yl)ethanone (0.17 g, 0.79 mmol) was next added, and the resulting mixture was heated at 100° C. for 2 h. The cooled reaction was diluted with EtOAc and washed with water. The organic layer was dried (MgSO4), filtered, and concentrated in vacuo. Flash column chromatography (20% to 80% EtOAc/Hexanes) afforded 1-(4-(2-(cis-3-(benzo[d]thiazol-2-ylamino)cyclobutoxy)pyridin-3-yl)-5,6-dihydropyridin-1(2H)-yl)ethanone as an off-white amorphous solid. [M+1]=421.0.
