Versuchsvorschrift

To a suspension of 2-fluoropyridine-3-carbonyl chloride (3.2 g, 20 mmol, Step D) and NaHCO3 (4 g, 48 mmol) in CH2Cl2 added in dropwise a solution of 4-tert butylaniline (3.0 g, 20 mmol). After the addition, the suspension was stirred at RT for 5 h. Solid inorganic salts were removed via filtration. The filtrate was concentrated to afford a brown solid as desired compound. MS: 273 (M+H). Calc'd. for C16H17FN2O—272.33.
