(I10B): To an oven dried 500 ml round bottom flask was added 7-bromo-2-chloro-N-ethyl-N-(4-methoxybenzyl)imidazo[2,1-f][1,2,4]triazin-4-amine (12.5 g, 31.5 mmol) and copper(i) cyanide (9.0 g, 100 mmol). The flask was caped under nitrogen and NMP (250 mL) was added. The mixture stirred 5 min at 25° C. and the flask was evacuated and back-filled with nitrogen 3×. The reaction stirred at 135° C. (oil bath) 21 hr. The reaction cooled to 25° C., diluted with ethyl acetate (500 ml) and filter through edit bed. The bed was washed with EtoAc 3×100 ml and the filtrate washed with water 1×300 ml and brine 3×150 ml. The organics dried with sodium sulphate and remove solvent. The material was crystallized from IPA and filtered to afford 2-chloro-4-(ethyl(4-methoxybenzyl)amino)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile (11 g).
