実験手順
To a suspension of LAH (1 g, 0.027 mol) in dry THF (70 mL) was added methyl 5-morpholin-4-ylnicotinate (4 g, 0.018 mol) in dry THF (10 mL) at −40° C. under stirring. The reaction mixture was stirred at this temperature for 2 h and then quenched with 6 mL of 10% aqueous NaOH solution at −40° C. The reaction mixture was allowed to stir at RT for 30 min, filtered through celite, washed with THF and concentrated to afford 2.8 g, (80%) of the title compound as a liquid.
