Participants

Reaction Steps

To a solution of N,N-diethyl-4-methoxy-2-methylbenzamide (1.00 g, 4.52 mmol) in THF (9 ml) at −78° C. was added dropwise tert-butyllithium 1.7 M in pentane (3.19 ml, 5.42 mmol) and the solution was stirred for 0.5 h before addition of 3-fluoro-4-methoxybenzonitrile (0.683 g, 4.52 mmol) in THF (9 ml). The resulting solution was warmed to rt and stirred for 16 h. The reaction mixture was quenched with water, neutralized with 1 N HCl. The precipitated solid was collected and washed with water to give 3-(3-fluoro-4-methoxyphenyl)-6-methoxyisoquinolin-1-ol (926 mg, 69% yield) as a solid after drying. MS: MS m/z 300.1 (M++1).
