Procedure:
A mixture of 5-amino-4-cyano-1-(2,3,4-trichlorophenyl)pyrazole (12.47 g) and 4-chlorobutyryl chloride (12.3 g) in dry acetonitrile (200 ml) was stirred and gently warmed to effect dissolution. The solution was cooled to room temperature and stirred, after 48 hours a further quantity of 4-chlorobutyryl chloride (6.15 g) was added and stirring continued for 24 hours. The solution was evaporated under reduced pressure to give an oil which was chromatographed using dichloromethane-ethyl acetate (19:1) as eluent. Evaporation of the eluate containing the fastest moving component gave 5-(4-chlorobutyramido)-4-cyano-1-(2,3,4-trichlorophenyl)pyrazole (5 g), m.p. 173°-174° C., after crystallisation from toluene, in the form of pale yellow crystals.

Procedure:
To a solution of tert-butyl {4-[2-(3-aminophenyl)ethyl]pyridin-2-yl}carbamate (160 mg, 0.51 mmol) and 2,4,5-trichloropyrimidine (98.3 mg, 0.54 mol) in N,N-dimethylformamide (2.3 mL) was added potassium carbonate (212 mg, 1.53 mmol). The resultant mixture was stirred at room temperature for 4 hours. The reaction mixture was filtered first to remove K2CO3, followed by quenching with water. EtOAc was added and the layers were separated. The aqueous layer was extracted with EtOAc twice. The combined organic layers were washed with water and then dried (Na2SO4), filtered and concentrated to give the residue, which was purified by trituration with cold EtOAc to give the desired product (123 mg, 36%) as an off-white powder.

Procedure:
N-(1,1-Dimethylprop-2-ynyl)-N-(4,5-dimethyl-1,3-dioxolan-2-ylmethyl)amine (10 grams), benzene (100 ml), water (100 ml) and sodium carbonate (8 grams) are charged into a glass reaction vessel equipped with a mechanical stirrer and thermometer. The reaction mixture is cooled to a temperature of 5° to 10° C. and α-bromopropionyl chloride (7 grams) is added dropwise with stirring. After the addition is completed stirring is continued until the reaction mixture reaches room temperature. After this time the organic phase is separated from the aqueous phase and is washed with water. The washed solution is then dried over anhydrous magnesium sulfate, filtered and stripped of solvent under reduced pressure to yield the desired product N-(1,1-dimethylprop-2-ynyl)-N-(4,5-dimethyl-1,3-dioxolan-2-ylmethyl)-α-bromopropionamide.
