Reaction Steps

Add 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (0.111 g; 1.5 equiv; 0.58 mmoles) to a solution of 2H-triazole-4-carboxylic acid (0.048 g; 1.1 equiv; 0.42 mmoles), 3-amino-1-[2-(2,3-dihydro-1H-inden-2-ylamino)-7,8-dihydropyrido[4,3-d]pyrimidin-6(5H)-yl]propan-1-one (0.13 g; 1.0 equiv; 0.39 mmoles), and N,N-dimethyl-4-pyridinamine, (0.0094 g; 0.2 equiv; 0.077 mmoles) in dichloromethane (1.28 mL). Stir the reaction at ambient temperature for 16 hours. Load the mixture directly onto a silica gel column and purify by column chromatography (0 to 10% methanol in ethyl acetate) to afford N-{3-[2-(2,3-dihydro-1H-inden-2-ylamino)-7,8-dihydropyrido[4,3-d]pyrimidin-6(5H)-yl]-3-oxopropyl}-1H-1,2,3-triazole-4-carboxamide (0.105 g; 63%) as a white solid: MS (m/z): 433(M+1).
