Procedure

Trans-5-amino-2-diphenylmethyl-tetrahydropyran 15 (0.1 g, 0.38 mmol) was reacted with 3,4-dichlorobenzaldehyde (0.066 g, 0.38 mmol) in the presence of glacial acetic acid (0.023 g, 0.38 mmol) in 1,2-dichloroethane (20 ml), and NaCNBH3 (0.03 g, 0.45 mmol) in methanol (5 ml) (Procedure D) to give compound 16i (0.12 g, 75%) as an oil.
