Procedure

4-(2-chloro-6-(piperidin-4-ylmethyl)pyrido[3,2-d]pyrimidin-4-yl)morpholine (40 mg) was added to a pre-stirred (15 minutes) solution of acetic acid (5 eq), 1-Hydroxybenzotriazole (HOBt, 1.2 eq.), N-(3-Dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (1.5 eq.), DIPEA (5 eq) in N,N-Dimethylformamide (DMF, 0.9 mL). The reaction was stirred overnight then extracted with Ethyl Acetate and brine. The organic layer was dried (Mg2SO4), filtered and concentrated to give quantitative yield of 1-(4-((2-chloro-4-morpholinopyrido[3,2-d]pyrimidin-6-yl)methyl)piperidin-1-yl)ethanone.
