Reaction Steps

Pd(PPh3)4 (1.9 g, 0.006 eq) and CuI (2.6 g, 0.05 eq) were suspended in DMF (350 ml). Methyl 2-iodobenzoate (70.8 g, 1 eq), but-3-yn-2-ol (32 ml, 1.5 eq), TEA (75 ml, 2 eq) were added under nitrogen atmosphere and the mixture was stirred at 60° C. for 6 hrs and at RT. overnight. The precipitated solid was filtered off, the mother liquors was diluted with a saturated solution of NaClaqueous and extracted with EtOAc (twice). The collected organic phases were dried over Na2SO4, filtered and concentrated under reduced pressure to give the title compound, as a brownish thick oil (47.7 g).
