Participants

Reaction Steps

To a solution of 6-(5-Isothiocyanato-2-methyl-phenyl)-2-[4-(4-methyl-piperazin-1-yl)-phenylamino]-7,8-dihydro-6H-pyrido[4,3-d]pyrimidin-5-one (50.0 mg, 0.089 mmol), and 2-Amino-phenol (9.73 mg, 0.089 mmol) in THF (5 ml) was added EDC.HCl (25.6 mg, 0.133 mmol), and the reaction mixture was refluxed for 12 hour under nitrogen atmosphere. After 12 hrs, the reaction mass was concentrated to dryness to get crude compound. The crude obtained was subjected to preparative HPLC. The desired compound i.e., 6-[5-(Benzooxazol-2-ylamino)-2-methyl-phenyl]-2-[4-(4-methyl-piperazin-1-yl)-phenylamino]-7,8-dihydro-6H-pyrido[4,3-d]pyrimidin-5-one was obtained as brown solid [54][Yield: 57.7 mg, 63.2%]
