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+). The mixture was filtered through celite extracted with chloroform The combined extracts were dried over MgSO4 filtered concentrated

Procedure: A solution of (1aS,5aR)-1,1,2-trimethyl-1,1a,5,5a-tetrahydro-3-thia-cyclopropa[a]pentalene-4-carboxylic acid (67 mg, 0.30 mmol), TBTU (106 mg, 0.33 mmol) and ethyl-diisopropylamine (169 μL, 0.99 mmol) in DMF (2 mL) is allowed to stand at rt for 10 min. A solution of 4-aminomethyl-2,6-dimethyl-phenol (45 mg, 0.30 mmol) in DMF (0.5 mL) is added and the mixture is allowed to stand at rt for 3 h. After the addition of formic acid (0.2 mL) the mixture is separated by HPLC to afford (1aS,5aR)-1,1,2-trimethyl-1,1a,5,5a-tetrahydro-3-thia-cyclopropa[a]pentalene-4-carboxylic acid 4-hydroxy-3,5-dimethyl-benzylamide (100 mg) as a colourless oil. LC-MS: tR=1.03 min, [M+1]+=356.23. to stand at rt for 3 h is separated by HPLC

Procedure: To a suspension of LiAlH4 (1.51 g, 39.8 mmol) in diethyl ether (40 mL) a solution of 4-hydroxy-3,5-dimethylbenzonitrile (4.89 g, 33.2 mmol) in diethyl ether (20 mL) and THF (10 mL) is added dropwise at rt. The mixture is stirred at rt for 22 h before it is cooled with an ice-bath and carefully treated with water (10 mL), acidified with 25% aq. HCl and diluted with water (30 mL). The mixture is extracted with diethyl ether. The etheral extract is discarded. The aqueous phase is basified to pH˜8 by adding solid NaHCO3, saturated with NaCl, and extracted with diethyl ether followed by EA. The combined organic extracts are dried over MgSO4 and evaporated to leave 4-aminomethyl-2,6-dimethyl-phenol (1.20 g) as a solid.
