実験手順

A solution of 450 mg (2 mmol) of [2-(2-chloro-5-nitro-pyridin-4-yl)-vinyl]-dimethyl-amine in a 20 mL of mixed solvent of MeOH—CH2Cl2 (1:1) was treated with 3 mL of morpholine. The reaction mixture was stirred at 65° C. for 8 h. Volatiles were then removed. CH2Cl2 (100 mL) and H2O (30 mL) were added. The organic layer was separated and washed with H2O (30 mL), brine (30 mL), dried over Na2SO4, and concentrated. The red powder was treated with 4.0 g (63 mmol, 32 eq) of ammonium formate and 10% Pd—C (120 mg). The reaction mixture was stirred at 65° C. for 30 min. The reaction mixture was then filtered through a pad of celite and concentrated to obtain a yellow solid. Column chromatography (silica, 5% MeOH/CH2Cl2) provided 210 mg (52% for 2 steps) of 5-morpholin-4-yl-1H-pyrrolo[2,3-c]pyridine as a yellow solid. TLC (silica, 5% MeOH/CH2Cl2): Rf=0.40. MS (electrospray): exact mass calculated for C11H13N3O, 203.11; m/z found, 204.2 [M+H]+.
