Reaction Steps

The product obtained from Example 193, Step C (240.0 mg, 1.0 mmol) was treated with THF/H2O (1:1, 10 ml). The mixture was stirred at 60° C. for 2 hr. The reaction mixture was extracted with EtOAc, washed with 1N HCl, H2O and brine. Reverse phase HPLC purification provided 4-(1-methoxycarbonyl-1-methyl-ethyl)-benzoic acid as white solid. MS found: (M+1)+=223.1.
