Triethyl amine (2.94 g, 29.00 mmol) was added in 15 min. Methanesulfonic acid chloride (2.61 g, 21.80 mmol) was added, and the mixture was stirred at +25° C. for 3 h. Dichloromethane (20 ml) and 1 M NaHSO4 solution (10 ml) were added and the layers were separated. Organic layer was washed with 1 M NaHSO4 solution (10 ml), water (10 ml) and saturated sodium chloride solution (10 ml), dried (Na2SO4), filtered and evaporated to dryness to give 3.08 g of the title compound.
