Reaction Steps

A solution of 6-cyclobutyl-3-(3,4-dihydro-2H-pyrido[3,2-b][1,4]oxazin-7-yl)-2-fluorophenol (50 mg, 0.17 mmol) and 2-(4-(bromomethyl)phenyl)acetic acid (38 mg, 0.17 mmol) in DMSO (1 mL) was treated with potassium tert-butoxide (38 mg, 0.33 mmol) and stirred for 16 hours at 80° Celsius. The reaction was then cooled to rt, filtered, and the filtrate subjected directly to HPLC purification to give (4-{[6-cyclobutyl-3-(3,4-dihydro-2H-pyrido[3,2-b][1,4]oxazin-7-yl)-2-fluorophenoxy]methyl}phenyl)acetic acid (8 mg, 9%).
