YieldReaction ConditionsOperation in experiment
(ii) Preparation of N-[3-chloro-4-[(3-fluorobenzyloxy)phenyl]-6-iodo-quinazolin amine (3)Into a one liter four-necked round bottomed flask, 50OmL of xylene, 50.0 g of N'-^-chloro- 4-(3-fluorobenzyloxy)phenyl)-N,N-dimethylformamidine obtained by the process given in example-(l), 40 g of <strong>[132131-24-9]2-amino-5-iodobenzonitrile</strong> obtained by the process given in above step (i) and 25 mL of acetic acid were charged under stirring. The reaction was maintained at reflux condition for 10 hours and the completion of the reaction was monitored by TLC. The solvent was distilled off completely under vacuum and cooled to room temperature. 100 mL of isopropylalcohol was added and adjusted the pH to basic (about 10) with aqueous ammonia solution. The mass was maintained at that temperature for about lhr. The mass was cooled to room temperature and filtered and dried to get 70.0 g of N-[3-chloro-4-[(3- fluorobenzyloxy)phenyl]-6-iodo-quinazolinamine as a pale yellow coloured crystalline powder.Purity: 99.43% by HPLC Melting point range: 222-225 C
