Procedure

To a solution of 45 mg (0.13 mmol) of tert-butyl [(2R,3S)-5-oxo-2-(2,4,5-trifluorophenyl) tetrahydro-2H-pyran-3-yl]carbamate and 27 mg (0.13 mmol) of 2-(trifluoromethyl)-5,6,7,8-tetrahydropyrido[3,4-d]pyrimidine in 2.0 mL of dry methanol was added 5.0 mg (0.039 mmol) of decaborane. The reaction mixture was stirred overnight and concentrated in vacuo, then purified by preparative thin layer chromatography using an Analtech® 1000 micron plate (5% methanol/methylene chloride, 1% concentrated ammonium hydroxide) to give the product which was stirred with hydrochloric acid in methanol (1.3M, 4 mL) for 1 h to give the title product. LC/MS 432.93 (M+1).
