95% In dichloromethane; at 0 - 20℃; B. To a stirred suspension of 2-aminophenol (365 mg, 3.35 mmol) in dichloromethane (7 mL) at 00C was added compound ethyl 2-chloroacetimidate hydrochloride (798 mg, 5.05 mmol) portion-wise. After 1 hour 25 min. at 00C, the mixture was stirred at ambient temperature overnight. The mixture was filtered through Celite and the filtrate was concentrated. The residue was purified by column (hexanes/EtOAc, 7/3) to afford 2-(chloromethyl)benzoxazole as a pale oil (533 mg, 95%).
86.5% With acetic acid; In dichloromethane; at 0 - 20℃; for 1.41667h; To a solution of 2-aminophenol (3.76 g,34.5 mmol) in methylene chloride at 0 C was added ethyl chloroacetimidate hydrochloride (7.98 g,50.5 mmol). After 85 min, the reaction mixture was allowed to warm to room temperature, while beingstirred overnight. The mixture was filtered over diatomite and concentrated to oil under reducedpressure. The resulting residue was purified by column chromatography on silica gel (petroleumether/acetone, 10:1 v:v) to obtain compound 3 as a white solid (5.00 g, 86.5%). m.p., 152-154 C;MS (+ESI) m/z 168.05 [M + H]+
75% at 0℃; for 6h; General procedure: General Method B: To the solution of substituted 2-aminophenol (1.0 equiv.) or substituted benzene-1, 2-diamine(1.0 equiv.) in DCM (or CH3OH), Int 1 (1.5 equiv.) was added and stirred at 0C overnight. The mixture was filteredwith celite. The filtrate was concentrated, purified by silica gel chromatography (EtOAc:hexane = 1:1) to afford thedesired products.
3.99 g (65%) In ethanol; dichloromethane; Step 1) Preparation of 2-(Chloromethyl)benzoxazole A mixture of o-aminophenol (4.00 g, 36.6 mmol) and ethyl chloroacetimidate hydrochloride (8.68 g, 54.98 mmol) in ethanol (55 mL) was heated at reflux for 18 hours. The reaction mixture was cooled to room temperature and vacuum filtered. The filtrate was concentrated in vacuo, diluted with dichloromethane and filtered again. The methylene chloride filtrate was dried (MgSO4) and concentrated to afford 3.99 g (65%) of product as a brown oil which was used directly in the next step. 1 H NMR (CDCl3): delta7.73 (m, 1H, ArH), 7.56 (m, 1H, ArH), 7.38 (m, 2H, ArH), 4.76 (s, 2H, CH2 Cl).

After gas evolution ceased, 2-(chloromethyl) benzoxazole (100 mg, 0.6 mmol) was added and the reaction mixture warmed at 60 C. for one hour. The reaction was then cooled, diluted with diethyl ether, the ether extract washed with water, dried (Na2 SO4), filtered and evaporated to give 151 mg of crude mixture. This mixture was flash chromatographed on silica gel, eluding with 0.5% methanol/chloroform. Combined appropriate fractions gave 46 mg (32%) of oily product.
