Reaktionsschritte
A 1M solution of lithium aluminum hydride in THF (11.80 mL, 11.80 mmol) was added to a solution of methyl 2-(5-tert-butyl-2-hydroxy-4-nitrophenyl)-2-methylpropanoate (5.36 g, 18.15 mmol) in THF (50 mL). The mixture was stirred at ambient temperature for 3 h, and then diluted with methanol. The mixture was acidified with 1N HCl (pH 1-2) and the aqueous phase was extracted with MTBE. The organic phase was dried in vacuo to afford 4-tert-butyl-2-(1-hydroxy-2-methylpropan-2-yl)-5-nitrophenol which was used without further purification in the next step. 1H-NMR (400 MHZ, DMSO-d6) δ 10.12 (s, 1H); 7.37 (s, 1H); 6.80 (s, 1H); 4.77 (s, 1H); 3.69-3.65 (m, 2H); 1.30 (s, 9H); 1.29 (s, 6H)
