Reaction Steps
To a solution of HCl salt of (1S,4S)-2,5-diaza-bicyclo[2.2.1]heptan-2-yl((1S,3R)-1-ethyl-3-((3S,4R)-3-methoxy-tetrahydro-2H-pyran-4-ylamino)cyclopentyl)methanone (118 mg, 0.33 mmol) in DMSO (2 ml) was added triethylamine (0.15 ml, 1.08 mmol) and the 2-chloro-4-(trifluoromethyl)pyridine (183 mg, 1.01 mmol). The reaction was heated to 120° C. for 15 hours. The reaction was cooled to room temperature, and added to stirring ice water. The mixture was extracted with ethyl acetate (3x). The combined organics were washed with brine, dried over MgSO4 concentrated under reduced pressure and purified with the Biotage (0-100% methanol/ethyl acetate, 15 column volumes) to give the product as a brown foam (40 mg 26%).
