Reaction Steps

2,6-di-t-butylphenol (1.7680 g, 8.66mmol) is placed in a flame dried RBF, and 2-(methylthio)acetic acid (0.80 mL, 9.19 mmol) is then added. This is then blanketed with argon and TFAA (1.30 mL, 9.20 mmol) is added via syringe at a fast rate. A small amount of CH2C12 is added to aid in mixing. The reaction quickly turns violet and darkens. It is followed by TLC using 10% EtOAc in hexanes. After 5 h, the reaction is carefully poured into 70 mL saturated bicarbonate and extracted with 2 portions of Et2O. The combined organics are washed with brine, filtered through cotton, dried over molecular sieves, then concentrated on a rotavap and dried under vacuum. This gives a white solid which can be crystallized from EtOAc/hexanes to give orange crystals, mp=108.5°-109.5° C.
