Reaction Steps

8-Methyl-1-oxo-2-o-tolyl-1,2-dihydroisoquinoline-3-carbaldehyde 4101 (2.4 g, 8.6 mmol) was dissolved in anhydrous THF (280 mL) and cooled to −78° C. under a nitrogen atmosphere. Methyl MgBr (2 M, 5 mL, 10 mmol) was added slowly, and the resulting mixture was stirred at −78° C. for 2 h. H2O (5 mL) was added and then the solution was poured into ice-water (200 mL) and extracted with ethyl acetate (3×50 mL). The combined organic layer was washed with brine, dried over Na2SO4 and filtered. The filtrate was concentrated in vacuo, and the residue product was purified by flash column chromatography on silica gel (10-50% EA/PE) to afford the product, 3-(1-hydroxyethyl)-8-methyl-2-o-tolylisoquinolin-1(2H)-one 4102 (1.8 g, 71% yield) as a white solid.
