To a solution of 3-bromo-10-piperidin-4-yl-10H-phenothiazine, 5e (10.5 mg; 0.029 mmol) and 2-pyridyl carboxaldehyde (9.3 mg; 0.087 mmol) in dichloroethane (120 μL) was added acetic acid (5 μL) and a solution of sodium triacetoxyborohydride (12 mg, 0.057 mmol) in DMF (100 μL). The mixture was stirred at rt for 18 h, quenched with water (50 μL), and lyophilized. The thus obtained crude 3-bromo-10-(1-pyridin-2-ylmethyl-piperidin-4-yl)-10H-phenothiazine, 1f was used as such for the next reaction.
