Preparation method of erlotinib (by machine translation)

2 -4 Difluoro 5 - 2 -dihydroquinazoline -4 ketone and a chlorination reagent are subjected to a condensation reaction in a solvent system; and the obtained 5 - [(6 ethynylphenyl) amino] 7 -3 difluoro quinazoline and diethylene glycol are subjected to an etherification reaction in a base reagent and a solvent system to obtain the erlotinib diecainide obtained by carrying out a cyclization 4 - reaction -4 - in an alkali reagent and a solvent system at a high temperature and carrying 4 - out -6 a 7 - cyclization reaction 3 - in a solvent system at a high temperature and carrying out a cyclization reaction in a 4 - solvent system 3 - at a high temperature.6 7 . The impurity is less and controllable, the next reaction can be directly carried out, the operation is simplified, the good yield can be obtained in each step, the process flow is simplified, and the safety and the environment protection are guaranteed.
