1.6 g (8.5 mmol) of 4-chloro-5-methoxy-6-methoxymethylpyrimidine, 1.5 g (8.5 mmol) of 4-amino-2-phenyltetrahydrothiophene (prepared from 2-phenyl-4-oxo-tetrahydrothiophene (cf. D. N. Reinhard, W. P. Trompenaars, I. Geevers, Synthesis 1978, 368) analogously to the route given in Example B) and 2 ml (14 mmol) of triethylamine were heated for 24 hours at 85° C. After cooling, the mixture was diluted with water and extracted with ether, and the organic phase was washed with saturated NaCl solution. After drying and concentrating, the residue was purified by column chromatography using petroleum ether/ethyl acetate (9:1). This gave 1.18 g (42% of theory) of a pale yellow syrup.
