| titleOfInvention | 9-[4-(3-chlor-2-fluor-phenylamino)-7-methoxy-quinazolin-6-yloxy]-1,4-diazaspiro[5.5]undecan-5-one dimaleate, use thereof as a drug, and production thereof |
| abstract | Disclosed is crystalline 9-[4-(3-chloro-2-fluorophenylamino)-7-methoxy-quinazolin-6-yloxy]-1,4-diazaspiro[5.5]undecan-5-one dimaleate of formula (I) optionally in the form of the tautomers thereof, wherein reflections in the X-ray powder diagram occur at dhkl values of 7.11, 5.77, 4.69, 4.36, 4.15, 3.85 and 3.61 Å, and has corresponding values 2theta of 12.43, 15.33, 18.92, 20.37, 21.38, 23.06 and 24.67. Also disclosed is a process for the stereoselective preparation of the crystalline compound of formula (I) starting from 1,4-cyclohexanedione-mono-ethyleneketal. Also disclosed is a process for the chlorination of tert-butyl (trans)-9-(4-hydroxy-7-methoxy-quinazolin-6-yloxy)-5-oxo-1-(2,2,2-trifluoro-acetyl)-1,4-diaza-spiro[5.5]undecane-4-carboxylate or tert-butyl (trans)-9-(4-oxo-7-methoxy-quinazolin-6-yloxy)-5-oxo-1-(2,2,2-trifluoro-acetyl)-1,4-diaza-spiro[5.5]undecane-4-carboxylate with a reactant selected from among N-chlorosuccinimide/triphenylphosphane oxalyl chloride, thionyl chloride, phosphorus oxychloride, phosphorus pentachloride, carbon tetrachloride/triphenylphosphane, dichlorotriphenylphosphorane and P,P-dichlorophenylphosphine oxide, to form tert-butyl (trans)-9-(4-chloro-7-methoxy-quinazolin-6-yloxy)-5-oxo-1-(2,2,2-trifluoro-acetyl)-1,4-diaza-spiro[5.5]undecane-4-carboxylate. Further disclosed are intermediates such as tert-butyl (trans)-9-(3-benzyl-7-methoxy-4-oxo-3,4-dihydro-quinazolin-6-yloxy)-5-oxo-1-(2,2,2-trifluoro-acetyl)-1,4-diaza-spiro[5.5]undecane-4-carboxylate and (trans)-9-[4-(3-chloro-2-fluoro-phenylamino)-7-methoxy-quinazolin-6-yloxy]-1-(2,2,2-trifluoro-acetyl)-1,4-diaza-spiro[5.5]undecan-5-one hydrochloride. |
