N,N-diethyl-3-hydroxybenzamide

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a solution of Compound 15a (0.68 g; 3.28 mmol) in CH2Cl2 (50 mL) was added BBr3 (1.0M in CH2Cl2) (16 mL; 16 mmol) dropwise at 0° C. The reaction was stirred at room temperature for 1 h. The mixture was quenched with saturated aqueous NaHCO3. The organic layer was dried over MgSO4 and concentrated to afford Compound 15b. The crude product was used in the next reaction without further purification. MS m/z 194.2 (M+H)+. The mixture was quenched with saturated aqueous NaHCO3 The organic layer was dried over MgSO4 concentrated
