To a solution of 26 (1.0 g, 3.9 mmol) in MeOH (20 mL) was added 20% Pd—C (200 mg), and the mixture was stirred vigorously under H2 (1 atm.) atmosphere at RT for 18 h. The reaction mixture was filtered through a pad of Celite® and concentrated in vacuo to afford 740 mg (82%) (1-(tetrahydro-2H-pyran-2-yl)-1H-benzo[d]imidazol-5-yl)methanamine (28) as yellow oil, which was used into the next step without further purification: MS (ESI) m/z=232.2 [M+1]+.
