To a solution of 3-bromo-10-piperidin-4-yl-10H-phenothiazine, 4i (11.2 mg; 0.029 mmol) and 3-furyl carboxaldehyde (8.4 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 (100μ). The mixture was stirred at rt for 18 h, quenched with water (50 μL), and lyophilized. The thus obtained crude 3-bromo-10-(8-furan-3-ylmethyl-8-aza-bicyclo[3.2.1]oct-3-yl)-10H-phenothiazine, 5i as a mixture of endo and exo isomers was used as such for the next reaction.
