With triphenylphosphine; diethylazodicarboxylate; 4-nitro-benzoic acid In tetrahydrofuran at 0 - 30℃; | 2.B Step. The compound of Step A (144. 5g, 0. 59 mol), triphenyl phosphine (200g, 0. 76 mol, 1. 29 eq), p- nitrobenzoic acid (150 g, 0. 9 mol, 1. 52 eq) and THF (2. 5 L) were mixed and cooled to 0°C. Diethyl diazodicarboxylate (120 mL, 0. 76 mol, 1. 29 eq) was added over 10 min. The reaction exotherme to 30°C and was allowed to cool to room temperature and stir overnight. The reaction was concentrated, the residue diluted with ether (1L) and the resulting suspension filtered. The filtrate was again concentrated, re-dissolved in CH2C12 and chromatographed (silica, linear gradient CH2C12 to 5% EtOAc/CH2Cl). The product cuts were combined and concentrated. The concentrate was flushed with ether then hexanes to afford a white slurry which was filtered and dried giving 218. 7g of the title compound as a white solid. | |
