1.5 g (5.14 mmol) of ethyl[(Z)-1-(2-chloro-4-fluorophenyl)-2-cyanoethenyl]carbamate (Example 36A) and 952 mg (5.14 mmol) of 1-(propan-2-yl)piperidine-4-carbohydrazide (Example 38A) were dissolved in 27 ml of N-methylpyrrolidone, and the mixture was stirred under argon at an oil bath temperature of 160° C. in a flask with fitted calcium chloride drying tube for 3 h. The reaction mixture was cooled to RT, water (50 ml) was added and the mixture was stirred for 15 min. The resulting precipitate was filtered off, washed with a little water and then dried under high vacuum. This gave 1.25 g (61% of theory) of the product.
