Participants

Reaction Steps

(S)-4-(2,2-Dimethyl-1,3-dioxa-8-azaspiro[4.5]decan-8-yl)-N2-[1-(4-fluorophenyl)ethyl]-N6-(pyrazin-2-yl)pyridine-2,6-diamine was obtained by the same process as in Example using 2,2-dimethyl-1,3-dioxa-8-azaspiro[4.5]decane instead of (S)—N-(pyrrolidin-3-yl)acetamide, and using 1,4-dioxane as a reaction solvent. 46 mg of the obtained compound was dissolved in 1 mL of chloroform, and 0.5 ml of 50% trifluoroacetic acid aqueous solution was added at 0° C. thereto, and the mixture was stirred. The solvent was distilled off under reduced pressure, and then the obtained residue was purified by silica gel column chromatography to obtain 21 mg of the objective compound as brown powder.
