实验步骤: Under argon, in a 500 ml round-bottomed flask equipped with a thermometer and a condenser, 10 g of (4-chloro-6-oxo-1,6-dihydropyrimidin-2-yl)acetic acid ethyl ester (example 25b, step 5b) and 9.6 g of morpholin-2-yl-methanol hydrochloride obtained previously are successively placed in 200 ml of DMSO and 16.1 ml of triethylamine. The reaction medium is heated for 22 h at 85° C. After returning to ambient temperature (20° C.), the reaction medium is poured into a saturated NaCl solution, and the mixture is extracted with 8×250 ml of ethyl acetate. The organic extracts are combined, dried over magnesium sulfate, filtered, and evaporated under reduced pressure. A solid is obtained which is slurried in diisopropyl ether containing 10% of methylene chloride. The solid is filtered off, and rinsed twice and then once with pentane. [4-(2-Hydroxymethylmorpholin-4-yl)-6-oxo-1,6-dihydropyrimidin-2-yl]acetic acid ethyl ester is isolated (1.9 g; yield=14%) in the form of a beige solid. obtained previously After returning to ambient temperature (20° C.) the mixture is extracted with 8×250 ml of ethyl acetate dried over magnesium sulfate filtered evaporated under reduced pressure A solid is obtained which The solid is filtered off rinsed twice

实验步骤: In an autoclave under an argon atmosphere at ambient temperature (20° C.), 215 ml of methanol, 1.7 g of palladium hydroxide (12135-22-7), 12.4 g of (4-benzylmorpholin-2-yl)methanol and 15 ml of 4M HCl are successively placed in dioxane. After the autoclave has been closed, the reaction medium is placed under 6 bar of hydrogen at 25° C. for 24 h. The reaction medium is filtered through Clarcel, rinsed several times with methanol; the filtrate is concentrated under reduced pressure. Morpholin-2-ylmethanol hydrochloride (9.65 g) is isolated in the form of a yellow oil. at ambient temperature After the autoclave has been closed The reaction medium is filtered through Clarcel rinsed several times with methanol the filtrate is concentrated under reduced pressure
