Reaction Steps

A mixture of 7-bromo-3-chloroisoquinoline (100 mg, 0.4 mmol) and sodium methoxide (113 mg, 2.1 mmol) in diglyme (1 mL) was heated to 150° C. for 1 hour. The reaction was cooled to room temperature and diluted with toluene and water. The layers were separated and the aqueous layer was extracted with toluene (3×). The combined organics were washed with water and brine, dried over sodium sulfate, filtered, and concentrated to an oil. The oil was dried under vacuum overnight to give the title compound (83 mg, 85%) as a yellow solid. +ESI (M+H+1) 240.1; 1H NMR (400 MHz, CDCl3, δ): 8.87 (s, 1H), 8.01-8.05 (m, 1H), 7.58-7.64 (m, 1H), 7.53-7.58 (m, 1H), 6.97 (s, 1H), 4.02 (s, 3H).
