Reaction Steps
4-(2-Chloro-6-(piperidin-4-ylmethyl)pyrido[3,2-d]pyrimidin-4-yl)morpholine from Example 148 (40 mg) was added to a pre-stirred (15 minutes) solution of 2-methylpropanoic acid (2 eq.), 1-Hydroxybenzotriazole (1.2), N-(3-Dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (1.5 eq.), diisopropylethylamine (DIPEA, 5 eq.) in N,N-Dimethylformamide (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)-2-methylpropan-1-one.
