Procedure

2-Methylsulfanyl-phenol (2.00 g, 14.29 mmol), 2-bromo-2-methyl-propionic acid, ethyl ester (28 g, 142 .8 mmol) and powdered K2CO3 (4.93 g, 35.7 mmol) were mixed (no solvent) and stirred at 105° C. for 8 hrs. After cooling, water and CHCl3 were added. The CHCl3 was separated, dried (MgSO4) and concentrated. Xylene was added and concentrated in vacuo (4 times) to remove the bromo ester. The resulting oil was chromatographed on silica, eluting with CH2Cl2 to obtain the title compound (2.30 g, 63% yield).
