Reaction Steps

A solution of t-butyl 6-(5-(cyanomethyl)thiazol-2-yl)pyridazin-3-yl((1-(3-fluoropyridin-2-yl)cyclobutyl)methyl)carbamate (1 g, 2 mmol) in HCl (30 mL, conc) was heated to 105° C. in a microwave reactor and stirred for 15 min. The reaction was concentrated to give 900 mg (2.3 mmol) of a crude reddish solid. To this solid was added methylamine hydrochloride (183 mg, 2.7 mmol), HOBt (365 mg, 2.7 mmol), EDC (516 mg, 2.7 mmol), DMF (30 mL), and TEA (1.3 mL, 9 mmol). The reaction was stirred at rt overnight. The reaction was then poured into ethyl acetate (200 mL), washed with water (3×100 mL), and the organic layer was separated, dried over Na2SO4, filtered, concentrated, and recrystallized from EtOAc to give 408 mg of 2-(2-(6-((1-(3-Fluoropyridin-2-yl)cyclobutyl)methylamino)pyridazin-3-yl)thiazol-5-yl)-N-methylacetamide as a white solid (M+H=413.3).
