실험 절차

In a 3 L fixed vessel, sodium thiomethoxide (21% in water) (216 g, 646.69 mmol) was added dropwise over 5 minutes to a stirred solution of a mixture of approximately two thirds (R)-(2-chloro-6-(3-methylmorpholino)pyrimidin-4-yl)methyl methanesulfonate and one third (R)-4-(2-chloro-6-(chloromethyl)pyrimidin-4-yl)-3-methylmorpholine (130.2 g, 431 mmol) and sodium iodide (1.762 ml, 43.11 mmol) in MeCN (1 L) at RT (temperature dropped from 20° C. to 18° C. over the addition and then in the next 5 minutes rose to 30° C.). The reaction mixture was stirred for 16 hours and then diluted with EtOAc (2 L), and washed sequentially with water (750 ml) and saturated brine (1 L). The organic layer was dried over MgSO4, filtered and then evaporated to afford (R)-4-(2-chloro-6-(methylthiomethyl)pyrimidin-4-yl)-3-methylmorpholine (108 g, 91%); 1H NMR (400 MHz, DMSO-d6) 1.20 (3H, d), 2.07 (3H, s), 3.11-3.26 (1H, m), 3.44 (1H, td), 3.53 (2H, s), 3.59 (1H, dd), 3.71 (1H, d), 3.92 (1H, dd), 3.92-4.04 (1H, br s), 4.33 (1H, s), 6.77 (1H, s); m/z: (ES+) MH+, 274.36.
