Yield: 81%

Reaction Conditions:

in tetrahydrofuran;water at 0 - 20;Inert atmosphere;

Steps:


(4-Chlorobenzyl)methyIamine (30)To a stirred solution of 4-chlorobenzylchloride (3.00 g, 18.63 mmol) in THF (300 ml) under N2 at 0 0C, was added methylamine solution in water (40% v/v) (9.03 mi, 93.48 mmol) and the reaction allowed to progress at room temperature overnight. The solvent was removed by rotary evaporation with water removed by azeotroping with toluene. The crude product was purified directly by column chromatography using EtOAc (100%) followed by EtOAc: MeOH: NEt3 (92: 5: 3) as eluent to give 30 as a yellow oil (2.49 g, 81%); 1H NMR (CDCi3, 300 MHz) δ 7.25 - 7.18 (4H, m), 3.66 (2H, s), 2.38 (3H, s), 1.65 ( 1H, s); 13C NMR (CDCI3, 100 MHz) δ 138.6 (IV), 132.6 (IV), 129.5 (2C), 128.4 (2C), 55.2, 35.8; HRMS (ESI): Found 156.0580 (M+). C8H10NCI (M+) requires 156.0556.
