Procedure
A solution of 4-Hydroxy-3,5-dimethyl-benzaldehyde oxime (1.0 grams, 6.06 mmole) in acetic acid (30 ml) and Zn dust (4.0 grams, 61.2 mmole) was stirred at ˜60° C. for 2 hours. The mixture was filtered through celite, basified by aqueous ammonium hydroxide and extracted with chloroform. The combined extracts were dried over MgSO4, filtered, and concentrated to give a foam (0.90 g). MW 151; MS (m/e) 151 (M+).
