To a solution of N,N-diethyl-4-methoxy-2-methylbenzamide (500 mg, 2.259 mmol) in THF (5 ml) at −78° C. was added dropwise tert-butyllithium 1.7 M in pentane (1595 μl, 2.71 mmol) and the solution was stirred for 0.5 h before addition of 3-fluoro-4-isopropoxybenzonitrile (405 mg, 2.259 mmol) in THF (5 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 washing with water to give 3-(3-fluoro-4-isopropoxyphenyl)-6-methoxyisoquinolin-1-ol (520 mg, 70% yield) as a solid after drying. MS: MS m/z 328.1 (M++1).
