Procedure

Triethylamine (0.64 g, 6.3 mmol) was added dropwise to a mixture of the amine hydrochloride salt (compound 4, 0.70 g, 3.1 mmol) and methane sulfonyl chloride (0.36 g, 6.3 mmol) in tetrahydrofuran (35 nL). After stirring at room temperature for 2 hours, the mixture was filtered, diluted with ethyl acetate, and washed with dilute hydrochloric acid, saturated sodium bicarbonate solution, and water, dried over magnesium sulphate, filtered, and evaporated to dryness. The residue was crystallized from ethyl acetate/heptane to give colorless crystals (0.39 g, 47%); mp 86-88° C.
