Reaction Steps
A solution of 2-amino-6-fluorophenol (14) (254 mg, 2 mmol) and methyl 2,2,2-trimethoxyacetate (15) (328 mg, 2 mmol) in 3 ml MeOH was heated in micro wave reactor at 140° C. for 1 h. After cooling down to r.t. crystals formed. Filtration followed by washing with MeOH furnished 208 mg of methyl 7-fluorobenzoxazole-2-carboxylate (16) as brown needles. Yield: 53.3%. LC-MS: calculated M=195.15; observed M=195.96.
