Preparation 26Synthesis of (6-chloropyridazin-3-yl)-[2-(indan-2-ylamino)-7,8-dihydro-5H-pyrido[4,3- djpyrimidin- 6-yl] methanone .Stir a suspension of 6-chloropyridazine-3-carboxylic acid (1.93 g; 1.20 equiv; 12.17 mmoles), N-indan-2-yl-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidin-2-amine (2.70 g; 1.00 equiv; 10.14 mmoles), and l-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (2.14 g; 1.10 equiv; 11.16 mmoles) in dichloromethane (25 mL) for 30 minutes. Concentrate the reaction mixture under reduced pressure and purify the residue by column chromatography (0 to 5% methanol/methylene chloride) to provide the title compound (3.70 g; 90%). MS (m/z): 407 (M+l).
As the paragraph descriping shows that 5096-73-1 is playing an increasingly important role.
