实验步骤: Production Example 3 was repeated except that 1-(4-methoxyphenyl)piperazine dihydrochloride and isovaleryl chloride were replaced with 1-(2,5-difluoro-4-methoxyphenyl)-piperazine (228 mg) and phenethylsulfonyl chloride (409 mg), respectively, to provide crude 4-(2,5-difluoro-4-methoxyphenyl)-1-phenethylsulfonylpiperazine (401 mg).

实验步骤: A solution of 2-phenylethanesulfonyl chloride (40.94 g) in THF (250 ml) was cooled to −20° C. before it was treated with sat. aq. ammonia (50 ml). The brown suspension was stirred at rt for 16 h. The mixture was neutralised with aq. HCl and the organic solvent was evaporated. The remaining suspension was diluted with water and extracted four times with EA. The organic layers were combined and evaporated to give 2-phenyl-ethanesulfonic acid amide (33.06 g) as orange solid. 1H-NMR(300 MHz, CDCl3): 3.15–3.21(m, 2H), 3.38–3.45(m, 2H), 4.59(s br, 2H), 7.21–7.37(m, 5H). the organic solvent was evaporated The remaining suspension was diluted with water extracted four times with EA evaporated

实验步骤: In analogy to the procedure described in example 20.4, 2-aminomethyl-3H-pyrimido[4,5-d]pyrimidin-4-one (example 20.3) was treated with 2-phenyl-ethanesulfonyl chloride [4025-71-2] to obtain 2-phenyl-ethanesulfonic acid (4-oxo-3,4-dihydro-pyrimido[4,5-d]pyrimidin-2-ylmethyl)-amide as light brown solid. MS: m/e=346.3 [M+H+].
