实验步骤: A mixture of ethyl 4-amino-3-hydroxy-phenylacetate (3.3 g, Reference Example 2) and o-tolylisothiocyanate (2.5 mL) in ethanol (150 mL) was stirred at room temperature for about 2 hours. After standing at room temperature overnight the mixture was evaporated and the residue was subjected to flash chromatography on silica eluting with a mixture of pentane and ethyl acetate (7:3, v/v) to give a yellow foam. A solution of this material in ethanol (150 mL was treated with dicyclohexylcarbodiimide (3.0 g) and the mixture was heated at reflux temperature for 2 hours. The mixture was evaporated and the residue subjected to short column chromatography on silica eluting with a mixture of 5-10% tert-butyl methyl ether in dichloromethane to remove dicyclohexylurea. The resulting light yellow oil was dissolved in ethanol (100 mL) and the solution was treated with sodium hydroxide solution (15 mL, 1M) then heated at reflux temperature for 2 hours. The reaction mixture was evaporated and the residue was dissolved in water. The solution was washed with ethyl acetate and the aqueous layer was acidified to pH 1 by addition of concentrated hydrochloric acid. The resulting white precipitate was collected by filtration, then washed thoroughly with water, and then dried to give the title compound (1.8 g) as a white solid.

实验步骤: A solution of ethyl 3-(4-amino-3-hydroxyphenyl)-propionate (1.94 g) in ethanol (50 ml) was treated with o-tolyl isothiocyanate (1.66 g) and then heated at 40° C. for 2 hours. The mixture was evaporated then treated with ethanol (50 ml), then with diisopropylcarbodiimide (3 mL) and then stirred at 40° C. for 1 hour. The mixture was evaporated and the residue was treated with diethyl ether (50 ml) then filtered. The filtrate was evaporated to dryness and the residue subjected to flash chromatography on silica eluting with a mixture of ethyl acetate and cyclohexane (2:3, v/v) to give the title compound (1.6 g) as a colourless oil. The mixture was evaporated then treated with ethanol (50 ml) The mixture was evaporated the residue was treated with diethyl ether (50 ml) then filtered The filtrate was evaporated to dryness the residue subjected to flash chromatography on silica eluting with a mixture of ethyl acetate and cyclohexane (2:3

To the reaction mixture, o-tolyl isothiocyanate (59.8 μl, 0.445 mmol) was added, followed by further stirring for 2 hours. The reaction mixture was ice-cooled, and quenched with water (1 ml). This was diluted with dichloromethane (10 ml), and washed with water (10 ml×2). After the organic layer was dried over sodium sulfate, the sodium sulfate was filtered off, and the filtrate was concentrated under reduced pressure, to obtain a crude product of 4-{2-[bis-(4-methoxy-benzyl)-amino]-pyrimidin-5-yl}-2-morpholin-4-yl-5,6-dihydro-pyrrolo[2,3-d]pyrimidine-7-carbothioic acid o-tolylamide as a brown solid (134 mg).
