65% | With palladium 10% on activated carbon; hydrogen; In 2-methoxy-ethanol; at 70℃; for 6.0h; | To a solution of tert-butyl 5H-pyrrolo[3,4-b]pyridine-6(7H)-carboxylate (1.50 g) in glycol monomethyl ether was added a catalytic amount of 10% Pd/C. The suspension was heated to 70 C. and stirred for 6 h under H2. The resulted mixture was cooled to rt, poured into 100 mL of water and extracted with CH2Cl2 (50 mL×3). The combined organic phases were dried over anhydrous Na2SO4 and filtered. The filtrate was concentrated in vacuo to give the title compound as pale yellow oil (0.95 g, 65.00%). The crude product was used for the next step without further purification. The compound was characterized by the following spectroscopic data: MS (ESI, pos. ion) m/z: 227.2 (M+1). |

0.163 g | With tris-(dibenzylideneacetone)dipalladium(0); sodium t-butanolate; CyJohnPhos; In toluene; at 20 - 110℃; for 16.0h;Inert atmosphere; | Step a. To a solution of 2-bromo-5-phenylthiazole (CAS Number 133311-51-0; 0.158 g, 0.660 mmol) in toluene (5 ml) was added <strong>[186203-81-6]tert-butyl octahydro-6H-pyrrolo[3,4-b]pyridine-6-carboxylate</strong> (CAS Number 186203-81-6; 0.150 g, 0.660 mmol) at rt. Sodium tert-butoxide (0.120 g, 1.30 mmol) was added to the reaction mixture at rt. The resulting reaction mixture was degassed for 15 min and then treated with Pd2(dba)3 (0.030 g, 0.033 mmol) and Cy-JohnPhos (0.011 g, 0.033 mmol). The resulting reaction mixture was heated at 110C for 16 h then cooled to rt and poured into water (50 ml). The obtained mixture was extracted with EtOAc (3 x 20 ml). The combined organic phase was dried over Na2S04, filtered and concentrated under reduced pressure. The residue was purified by flash chromatography (2% MeOH in DCM) yielding tert-butyl l-(5-phenylthiazol-2-yl)octahydro-6H- pyrrolo[3,4-b]pyridine-6-carboxylate (0.163 g, 0.422 mmol).
