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 (2658 μl, 4.52 mmol) and the solution was stirred for 0.5 h before addition of morpholine-4-carbonitrile (253 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 and washed with water to give 6-methoxy-3-morpholinoisoquinolin-1-ol (350 mg, 60% yield) as a solid after drying.
