Reaction Steps

A mixture of methanol (100 mL) and ethyl acetate (100 mL) was added to the ethyl 2-(4-(difluoromethoxy)-8-nitrodibenzo[b,d]furan-1-yl)1,3-oxazole-4-carboxylate (0.8 g, 1.91 mmol) from step 7 of example 47. To the reaction mixture, palladium-carbon (0.30 g) was added. The reaction mixture was transferred to the hydrogenation flask and hydrogenation was performed at room temperature (40 psi-hydrogen) for 2 hours. The reaction mixture was filtered through celite. The filtrate was evaporated at reduced pressure to give the desired product. Yield—87.5%. Rf—0.5 (Ethyl acetate:Hexane (1:1)
