The present invention relates to a novel method for producing 3-alkoxycarbonylmethyl-3,4-dihydro-fused pyrimidine compounds. All of the compounds of the present invention in which the A moiety constitutes a thiophene ring are novel compounds. Also, some of the compounds that make up the benzene ring are
No. 51-70797 only discloses it without describing any specific physical properties. The compound of the present invention is an important intermediate in the production of the compound represented by formula (). For example, when the compound () of the present invention is heated with ammonia in a sealed tube in an insoluble solvent such as methanol, a compound of formula () is obtained. This compound exhibits extremely strong platelet aggregation inhibitory effects. Regarding the method for producing the compound of the present invention, a compound in which the A moiety constitutes a benzene ring is described in JP-A-51-70797, but the final target product is the formula ()
Since the production of this compound requires an unnecessarily roundabout process, it has little practical value as an intermediate. Therefore, the present inventors prepared a novel compound of the formula () in acetone, methyl ethyl ketone, or other inert solvent in the presence of an alkali carbonate, and prepared a halogenoacetic acid ester of the formula () for several hours to 20 hours.

物を合成した。以下表にまとめる。[Formula] The moieties X 1 , X 2 and R are the same as above. ) As a result of further study of this reaction, the present inventors were able to discover a more advantageous method and complete the present invention. That is, the present invention provides novel compounds of formula (),
This is a method for producing a compound of formula () by reacting 2-halogeno-3,4-dihydro condensed pyrimidines with halogenoacetate () in the presence of a phase transfer catalyst. Examples of the phase transfer catalyst include tetrabutylammonium iodide, benzyltriethylammonium bromide, benzyltrimethylammonium chloride, benzyltriethylammonium chloride, decyltriethylammonium bromide, and tetrabutylphosphonium bromide. The amount of these compounds to be used may be a catalytic amount, but as a guide, it is usually sufficient to use approximately 0.5% to 5% mole based on the compound. The reaction is carried out by dissolving or suspending the compound of formula () in an organic solvent that is uniformly immiscible with water, such as benzene, chloroform, methylene chloride, etc., and mixing this with an aqueous alkali hydroxide solution in an amount of 2 to 10 times the molar amount of the compound of formula. The reaction is completed in several minutes to tens of minutes at room temperature, and the compound of formula () is obtained in a good yield of 80 to 95%. The characteristics of this reaction are that the reaction conditions are mild and post-treatment is easy, so the target product can be isolated in good yield. That is, in the method of the present invention, the reaction proceeds at room temperature, whereas the reaction in the presence of an alkali carbonate (hereinafter referred to as the previous reaction) requires heating. Furthermore, the reaction time for the method of the present invention is several minutes to several tens of minutes, whereas the above reaction requires 20 hours. As described above, when the method of the present invention is used, the reaction can be carried out under mild conditions. Furthermore, in the method of the present invention, post-treatment of the reaction may be carried out by washing with water immediately after the completion of the reaction, but in the previous reaction, inorganic salts were removed by filtration and the solvent was distilled off before washing the extract. It requires operations such as removal and extraction, which is more complicated. Due to these characteristics, especially when the method of the present invention is applied as an industrial manufacturing method, it becomes possible to save labor in the manufacturing process. Next, the present invention will be explained using specific examples, but these are not intended to limit the present invention. Example 1 2.27 g of 2-chloro-3,4,5,6,7,8-hexahydro[1]benzothieno[2,3-d]pyrimidine, tetra-n-butylammonium iodide (hereinafter abbreviated as TBAI). ) was added to a mixture of 5 ml of 10N sodium hydroxide and 50 ml of methylene chloride, and 1.84 mg of ethyl bromoacetate was added under a nitrogen stream.
Add g under stirring. After stirring for 5 minutes, water was added to the reaction solution, the organic layer was separated, washed with water, dried, and the solvent was distilled off. 7,8

In addition, 2.85 g (91%) of crystalline material can be isolated by filtering it with ethanol. Melting point 105-110℃ (decomposition).

Add 400ml of sodium borohydride while stirring.
Add g little by little. After the addition was completed, stirring was continued for 15 hours at 45-50°C, and then the solvent was distilled off. After adding water to the residue and stirring well, the insoluble matter was filtered and washed thoroughly with water to obtain crude 2-chlor. 3, 4, 5, 6,
