Procedure

The title compound was prepared as described in Example B(53), using 7-(chloromethyl)-3-methyl-5H-(1,3]thiazolo[3,2-a]pyrimidin-5-one (prepared according to a reported procedure: Doria, G.; Passarotti, C.; Sala, R.; Magrini, R.; Sberze, P.; Tibolla, M.; Cesarani, R.; Arcari, G.; Castello, R.; Toti, D. Farmaco Ed. Sci. 1985, 40, 885) in place of 5-(chloromethyl)-1,3-dimethyl-1H-1,2,4-triazole, and using 6-{-[3-chloro-4-(cyclopropylmethoxy)phenyl]ethyl}-6-cyclopentyldihydro-2H-pyran-2,4(3H)-dione (from Step 4, below) in place of 6-[2-(3-chloro-4-methoxyphenyl)ethyl]-6-cyclopentyldihydro-2H-pyran-2,4(3H)-dione. Yield: 1%.
