Procedure
Using the procedure of Example 1, Step A and employing 50.0 g (252.45 mmol) of 3-amino-6-chloro-4-fluorophenol hydrochloride, 80% propargyl bromide (60.07 g, 504.9 mmol), and potassium carbonate (69.8 g, 504.9 mmol) in acetonitrile (200 mL), the title compound was obtained as a yellow solid (16.2 g), m.p. 62°-64° C. IR (nujol, era-1), NH2 (3298.0), triple bond (2117.6). 1H NMR was consistent with the structure.
