To a stirred solution of 2-aminophenol (10 g, 9.2 mmol) in DCM (92 mL) at 0° C. was added 2-bromoisobutyryl bromide (11.4 mL, 9.17 mmol) followed by triethyl amine (12.7 mL, 9.2 mmol) and stirred the reaction mixture at 0° C. for 4 h. Reaction mixture was diluted with DCM 100 mL and then washed with water 100 mL dried over sodium sulfate, concentrated on rotavap to give 2-Bromo-N-(2-hydroxy-phenyl)-2-methyl-propionamide (21.8 g) brown solid which was used for next reaction without purification
