실험 절차

A suspension of the compound of step B (3.200 g, 11.38 mmol) in 3 ml of 85% phosphoric acid was immersed in an oil bath preheated to 130° C. for 30 minutes. The reaction mixtures was cooled and poured onto crushed ice and stirred until solid formed and ice melted. The solid was filtered, washed with water to give a tan solid, the title compound, which was purified through silica gel column chromatography to give a tan solid. 1H NMR (CDCl3) δ 1.92(s, 6H), 2.32(s, 3H), 2.41(s, 3H), 2.45(s, 3H), 2.46(s, 3H), 6.42(d, 1H), 6.95(s, 2H) ppm.
