Reaction Steps

LAH (87 mg, 52.63 mmol) was taken in dry THF (10 mL) under inert atmosphere stirred for 10 min, 8-methyl-5-(2-methyl-1-oxo-1-(pyridin-4-yl)propan-2-yl)-3,4-dihydro-1H-pyrido[4,3-d]indole-2(5H)-carbaldehyde (0.33 g, 0.914 mmol) was added portionwise and stirred at RT for 1 h. The reaction was monitored by TLC. LAH was quenched with sat. sodium sulfate (aqueous) at 0° C., filtered the reaction mass. The filtrate was extracted with EtOAc, dried over anhydrous sodium sulfate and evaporated to dryness to afford 0.24 g of the title compound as a yellow sticky solid. 1H NMR (CDCl3, free base) δ (ppm): 8.36 (d, 2H), 7.20 (s, 1H), 7.10 (d, 1H), 7.0 (d, 1H), 6.78 (d, 2H), 3.78 (s, 2H), 3.60 (s, 3H), 2.82 (m, 1H), 2.74 (m, 1H), 2.60 (m, 1H), 2.50 (s, 3H), 2.42 (s, 3H), 2.30 (m, 1H), 2.19 (s, 3H).
