반응 단계

To a solution of 4-Isopropoxy-benzoic acid methyl ester (2.2 g, 11.2 mmol, 1.0 eq) in dry toluene (15 mL) under N2, NaH (50-60% dispersion in mineral oil, 1.1 g, 22.4 mmol, 2.0 eq) was added. The mixture was heated at 80° C. and then dry CH3CN was added dropwise (2.8 mL, 56.0 mmol, 5.0 eq). The reaction was heated for 18 hours, then was allowed to cool down to room temperature and acidified with HCl 2N. The organic phase was recovered and 2.0 g of crude were obtained and it was used for cyclization without further purification.
