Definitions
- lapatinib aldehyde which is frequently referred to as lapatinib aldehyde and which is used as the key intermediate in the production of lapatinib of formula II.
- This drug belongs to the drug group called protein kinase inhibitors and has been approved for treatment of metastatic breast tumours under the name TYKERB.
- the invention provides an improved process of producing lapatinib aldehyde of formula I
- R 1 , R 2 , R 3 and R 4 is H, or a C1-C4 (un)branched alkyl and wherein X is either a bond, or CR 5 R 6 , wherein R 5 and R 6 is H, or a C1-C4 (un)branched alkyl.
- the coupling is carried out at the boiling temperature of the solvent or mixture used, or at a temperature close to the boiling point, e.g., in the range of from 68°C to 78°C.
- the amount of the respective boronic acid is often important for the course of the Suzuki coupling.
- reactions that are sensitive to the ratio of the coupling components the fact that boronic acids are not completely stable and tend to form the corresponding dehydrated substances, including cyclic boroxines, represents a problem. Even though some of such derivatives are also able to provide products of Suzuki couplings, the exact ratio of the boron component to the halogenated component cannot be easily established.
- One of the possibilities of ensuring an exact ratio of the boron component to the halogenated component consists in using stable cyclic boronates of the general formula VII
- R 1 , R 2 , R 3 and R 4 is H, or a C1-C4 (un)branched alkyl and wherein X is either a bond, or CR 5 R 6 , wherein R 5 and R 6 is H, or a C1-C4 (un)branched alkyl,
- Another aspect of this invention provides new cyclic boronates of formulae Vila, Vllb and Vile,
- X CR 5 R 6 , wherein R 5
- R 4 H
- X CH 2 , which are especially suitable as stable cyclic boronates for use in the Suzuki coupling.
- lapatinib aldehyde of formula I preferably isolated in the form of a salt with p-toluenesulfonic acid (PTSA), also in a sufficient purity for further pharmaceutical use.
- PTSA p-toluenesulfonic acid
- the aldehyde of formula I can be converted to lapatinib of formula II and/or its salts by commonly known methods such as, e.g., described in EP1 294 715.
- A/,A/-diisopropylethylamine (0.13 ml, 0.73 mmol, 1.15 equiv.) and ethanol (4.8 ml) were added to a mixture of the boronic acid VI (120 mg, 0.86 mmol, 1.35 equiv.), Ill (322 mg, 0.64 mmol, 1 equiv.), 10 % Pd/C (8.8 mg, 0.008 mmol, 1.3 mol. %) and the resulting suspension was refluxed for 3 hours. After cooling to the room temperature the yellow suspension was filtered through kieselguhr and washed with methanol (4 X 3 ml).
- Triethylamine (0.2 ml) was added to a mixture of the boronic acid VI (104 mg, 0.74 mmol, 1.5 equiv.), Ill (250 mg, 0.49 mmol) and 10 % Pd/C (13 mg, 0.012 mmol, 2.5 mol. %), DME (4 ml) and methanol (2 ml) and the resulting substance was stirred at the temperature of 50°C for 14 hours. After working, 184 mg (78%) of a yellow powdery substance was obtained containing 91% of the title compound I and 8% of the unreacted input substance III according to HPLC.
- Acetic acid 0.5 ml, 8.44 mmol, 4 equiv.
- A/-ethyldiisopropylamine (1.47 ml, 8.44 mmol, 4 equiv.) were added dropwise to a suspension of the aldehyde I (1 g, 2.11 mmol) and 2-(methylsulfonyl)ethaneamine hydrochloride (0.54 g, 3.37 mmol, 1.6 equiv.) in THF (10 ml) at the room temperature.
- reaction mixture was stirred at 40°C for 1 h, cooled to 20°C, a solution of NaBH(OAc) 3 (0.9 g, 4.25 mmol, 2 equiv.) in THF (4.2 ml) was added and the resulting mixture was stirred at 20°C for 3 h. Then, a 1.25M solution of NaOH (16 ml) was added dropwise, the mixture was stirred at 20°C for 30 min, the product was extracted to ethyl acetate (3 x 8 ml), the organic layer was dried over MgS0 4 , filtered and evaporated at a reduced pressure.

Abstract
La présente invention porte sur un procédé de production du composé de formule I, consistant à coupler le dérivé iodé de formule III avec des dérivés de l'acide boronique, le couplage étant catalysé par des catalyseurs au Pd appropriés dans un solvant, les dérivés de l'acide boronique étant des boronates cycliques représentés par la formule générale VII, dans laquelle R1, R2, R3 et R4 représentent chacun H ou un groupe alkyle en C1-C4 ramifié ou non ramifié et X représente soit une liaison soit CR5R6, R5 et R6 représentant chacun H ou un groupe alkyle en C1-C4 ramifié ou non ramifié. L'invention porte également dans d'autres aspects sur des boronates cycliques et sur l'utilisation du composé de formule I.
