Reaction Steps

To a solution of [2-(3,4-dichloro-phenoxy)-5-(4-morpholin-4-yl-but-1-ynyl)-benzyl]-methyl-carbamic acid tert-butyl ester (95.6 mg, 0.18 mmol) in DCM (2 mL) was added TFA (1 mL). After 30 min, the mixture was concentrated and the residue was purified by FCC to give the desired product (67.7 mg, 89%). MS (ESI): mass calcd. for C22H24Cl2N2O2, 418.12; m/z found, 419.3 [M+H]+. 1H NMR (CDCl3): 7.49-7.47 (m, 1H), 7.37 (d, J=8.8, 1H), 7.27 (dd, J=8.3, 2.0, 1H), 7.02 (d, J=2.8, 1H), 6.82-6.78 (m, 2H), 3.75-3.69 (m, 6H), 2.70-2.64 (m, 2H), 2.62-2.57 (m, 2H), 2.55-2.51 (m, 4H), 2.42 (s, 3H), 1.80-1.69 (m, 1H).
