A solution of 3-chloro-5,6-dihydro-[1]pyrindin-7-one (34.5 mg, 0.21 mmol) and (R)-5-(5-amino-2-fluoro-phenyl)-5-methyl-morpholin-3-one (50.1 mg, 0.22 mmol) in a mixture of methanol (7.3 ml) and dichloromethane (0.9 ml) was treated with decaborane (6.9 mg, 0.21 mmol). The reaction mixture was stirred at room temperature for 22 hours. For the workup, the mixture was poured into a saturated aqueous solution of sodium hydrogen carbonate, thereafter extracted with ethyl acetate. The combined organic layers were dried over sodium sulphate, then evaporated at reduced pressure. The crude material was purified by flash chromatography on silica gel using a gradient of heptane/ethyl acetate=100:0 to 20:80 as the eluent. The (R)-5-[5-((RS)-3-chloro-6,7-dihydro-5H-[1]pyrindin-7-ylamino)-2-fluoro-phenyl]-5-methyl-morpholin-3-one was obtained as an orange solid (50 mg, 71%); (calculated) C19H19ClFN3O2 [375.83]; (found) [M]+=376, [M+2]+=378.
