Reaction Steps

Add N-indan-2-yl-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidin-2-amine (4.2 g, 15.8 mmol) to a mixture of 2-[2-(1H-triazol-5-yl)ethoxy]acetic acid (2.7 g, 15.8 mmol), 1-hydroxybenzotriazole (3.20 g, 23.7 mmol), and dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (5.44 g, 28.4 mmol) in dichloromethane (40 mL) at 25° C. Add triethylamine (4.40 mL, 31.6 mmol) to the reaction mixture and stir for 16 h. Wash with water (2×50 mL) and concentrate the organic layer. Purify by silica gel column chromatography, eluting with ethyl acetate/methanol, to give the title compound (4.0 g, 60%) as a solid. MS (m/z): 420 (M+H).
