Reaction Steps

A mixture of 76 mg of 2-{[4-(1-formyl-1,7-diazaspiro[4.4]non-7-yl)-2-(propan-2-yloxy)phenyl]amino}-7-(2-methoxyphenyl)thieno[3,2-d]pyrimidine-6-carboxamide and 2 ml of 5N sodium hydroxide in 15 ml of methanol is stirred at ambient temperature for 3 hours, and then maintained at reflux for 1 h 30. The mixture is stirred at AT for 15 h and then again maintained at reflux for 5 h 30. The reaction medium is then run into 20 ml of water and then the methanol is eliminated by concentration under reduced pressure. The resulting aqueous phase is washed several times with dichloromethane (3 times 20 ml) and then acidified so as to obtain a pH with a value of about 7/8, and then the aqueous phase is extracted a further three times with 20 ml of dichloromethane. The combined organic phases are dried over magnesium sulfate, filtered and concentrated under vacuum, so as to obtain 72 mg of 2-{[4-(1,7-diazaspiro[4.4]non-7-yl)-2-(propan-2-yloxy)phenyl]amino}-7-(2-methoxyphenyl)thieno[3,2-d]pyrimidine-6-carboxylic acid in the form of a brown solid.
