Participants

Reaction Steps

AcCl (0.547 mL, 7.70 mmol) was added to a sol. of 3-(tert-butyl-dimethyl-silanyloxymethyl)-4-chloro-benzylamine (2.00 g, 7.00 mmol) and DIPEA (4.80 mL, 28.0 mmol) in CH2Cl2 (70 mL) at 0° C. The mixture was stirred for 1 h while warming up to rt. CH2Cl2 (30 mL) was added, and the mixture was washed with aq. sat. NH4Cl (2×), aq. 1M NaOH (1×) and brine (1×). The org. layer was dried over MgSO4, filtered, and the solvents were removed under reduced pressure. Purification of the crude by FC (EtOAc/heptane 60:40) yielded the title compound (2.10 g, 91%). LC-MS: tR=1.07 min; ES+: 369.19.
