Procedure

Dimethylamine hydrochloride (0.10 g, 1.24 mmol) and 60B (0.16 g, 0.41 mmol) were mixed in DCM (5 ml). Triethylamine (0.290 ml, 2.07 mmol) was added and the mixture was stirred at RT for 2.5 h. More of triethylamine (0.290 ml, 2.07 mmol) and dimethylamine hydrochloride (0.10 g, 1.24 mmol) were added. The mixture was stirred overnight at RT and then diluted with DCM (10 ml). The mixture was washed with water, filtered through a phase separator and then evaporated. The residue was purified by column chromatography eluting with NH3 in MeOH (2M)/DCM (1:99, 2:98). There was obtained 0.14 g (84%) of 60 as a solid. 1H NMR (500 MHz, CDCl3): δ 2.20 (s, 6H), 3.38 (s, 2H), 4.16 (m, 2H), 4.61 (m, 2H), 5.07 (m, 1H), 7.50 (t, 2H), 7.56 (t, 1H), 8.12 (d, 2H), MS (APCI+) m/z 395 [M+H]+, LC purity: 97%.
