Reaction Steps

To a solution (R)-5-(5-bromo-2-fluorophenyl)-5-methyl-5,6-dihydro-2H-1,4-thiazin-3-amine (910 mg, 3 mmol, Eq: 1.00) and triethylamine (607 mg, 836 μl, 6.00 mmol, Eq: 2) in dichloromethane (30.0 ml) at 23° C. was added 4,4′-dimethoxytrityl chloride (1.12 g, 3.3 mmol, Eq: 1.1) and the mixture was stirred at 23° C. for 2 h. The solution was concentrated in vacuum and directly subjected to silica gel flash chromatography with n-heptane and ethyl acetate to give the (R)—N-(bis(4-methoxyphenyl)(phenyl)methyl)-5-(5-bromo-2-fluorophenyl)-5-methyl-5,6-dihydro-2H-1,4-thiazin-3-amine (1.67 g, 2.76 mmol, 91.9% yield) as an off-white foam. MS (ISP): m/z=605.1 [M+H]+ and 607.2 [M+2+H]+.
