Procedure:
A mixture of 8-(2-bromo-4-isopropyl-phenyl)-4-chloro-2-methyl-pyrrolo[1,2-a]pyrimidine-6-carbonitrile (300 mg), 1-propyl-butylamine (267 mg), N,N-diisopropylethylamine (300 mg) in ethanol (1.0 mL) was heated at reflux overnight. The reaction mixture was cooled to room temperature, poured into a saturated aqueous sodium hydrogencarbonate, and then extracted with chloroform. The organic layer was dried over anhydrous sodium sulfate and filtered. The filtrate was concentrated under reduced pressure and purified by a silica gel column chromatography (silica gel: Wako Gel (C200), eluent: hexane/ethyl acetate=20:1) to give 8-(2-bromo-4-isopropyl-phenyl)-2-methyl-4-(1-propyl-butylamino)-pyrrolo[1,2-a]pyrimidine-6-carbonitrile (321 mg) as a pale brown solid.

Reaction time: 0.5 h

Procedure:
A 2-liter multineck flask with distillation bridge and reflux divider, 20 cm packed column, stirrer, dip tube, dropping funnel, and thermometer was charged with 679 g (3.5 mol) of dimethyl terephthalate (Oxxynova), 1.7 g of tetrabutyl orthotitanate (0.25% by mass based on DMT, DuPont, Tyzor TnBT) and, to start with, 200 g out of a total of 748 g (8.5 mol) of n-pentanol (>99% purity, FLUKA), and this initial charge was heated slowly until the DMT forms a homogeneous mixture with the alcohol, at which point the stirrer was switched on. The reflux divider was set so that the overhead temperature remained at a constant level of approximately 65° C. (the boiling point of methanol). From a liquid-phase temperature of approximately 185° C., the remaining alcohol was slowly run in at a rate such that the temperature in the flask did not fall below 180° C. and a reflux sufficient for the distillation was maintained. The distillate removed was analyzed by GC for the amount of methanol separated off. After a major fraction of the methanol (approximately 90% of the anticipated 7 mol of methanol) had been taken off, a sample was taken from the reaction flask every 30 minutes and analyzed by GC. Transesterification was at an end when the amount of dimethyl ester and mixed ester(methyl pentyl) in total had dropped below 0.3% by mass (approximately 8 to 9 hours).

Procedure:
A solution of 122 g of potassium tert.-butylate in 720 ml of tetrahydrofuran was added with stirring under an inert atmosphere at -20°C to a mixture of 95 g of methyl isopropyl ketone and 185 g of tert.-butyl dichloroacetate and the mixture was allowed to return to room temperature and was stirred for 2 hours. The mixture was poured into iced water and stirred after which the organic phase was removed, washed with aqueous sodium chloride solution and dried over magnesium sulfate.

Procedure:
A mixture of 9.46 g of 3-(5-chloropentyl)-4-methyl-2,5-furandione and 8.13 g of 4-amino-2-(trifluoromethyl)benzonitrile in 22 ml of ethanol was mixed under a nitrogen atmosphere with 2.5 g of an activated molecular sieve (0.3 nm), and it was stirred for 2 days at 90° C.
