Versuchsvorschrift

A mixture of 4-benzylthio-5-methoxycarbonyl-2,6-dichloropyrimidine and 4,6-dibenzylthio-5-methoxycarbonyl-2-chloropyrimidine (prepared in the above (3)) 97 mg, 4-hydroxypiperidine 29 mg, triethylamine 29 mg and toluene 2.5 mg is stirred at room temperature for 4 hours. Further, 4-hydroxypiperidine 3 mg and triethylamine 3 mg are added thereto, and the mixture is stirred for 30 minutes. The reaction mixture is diluted with a 10% aqueous citric acid solution and extracted with ethyl acetate. The organic layer is washed, dried and concentrated in vacuo to give 4-benzylthio-5-methoxycarbonyl-6-(4-hydroxypiperidine-1-yl)-2-chloropyrimidine as a colorless caramel, 120 mg.
