Synthesis of compound 34-2 (0476) To the solution of 34-1 (2.0 g, 9.259 mmol) in MeOH (20 mL) was added 10percent Pd/C (0.2 g) purged with NStep 4. 4-(Pyridin-3-yloxy) aniline. 3-(4-nitrophenoxy)pyridine (10.2 g, 47.18 mmol) was dissolved in 100 mL MeOH, followed by addition of Pd/C powder (10percentwt, 1.1 g). The reaction mixture was stirred at r.t. under Hb) Compound 5 was hydrogenated at room temperature using PD/C in MEOH/THF.

Yield : 37.14 g (95percent) of 6, pale-brown crystalsA solution of 3- (4-nitrophenoxy)pyridine g, 23.13 mmol) in EtOAc (100 mL) in a 250 ml Parr bottle was purged with nitrogen. To this solution was added EtOAc-moistened 10percent Pd/C catalyst (500 mg, 10percent by weight). The reaction flask was placed in a Parr hygrogenation apparatus, purged with nitrogen (5x), evacuated, and then pressurized to 40 psi with hydrogen and shaken for 3.5 h. The reaction mixture was then purged with nitrogen, and filtered through a pad of Celite , rinsing with ethyl acetate (3x) and ethanol (3x). The filtrate was evaporated at reduced pressure to give a brown crystalline residue. The residue was stirred in diethyl ether at room temperature for 16 h and then filtered to provide 4.11 g (95percent) of the desired product as light brown crystals.
