Procedure

A mixture of iron powder (0.071 g, 1.27 mmoles) in acetic acid (2 ml) was heated to 55° C. for 15 minutes. Water (2 ml) was then added and oil bath was turned off. A solution of 8-(4-(3,6-dihydro-2H-pyran-4-yl)-6-(4-nitrophenyl)-1,3,5-triazin-2-yl)-3-oxa-8-azabicyclo[3.2.1]octane (0.100 g, 0.253 mmol) in ethyl acetate (2 ml) was then added to this warm solution over 5 minutes. The mixture was cooled to RT and allowed to stir for 16 hours. The mixture was extracted with ethyl acetate by decantation (4×) into a sep. funnel containing saturated aqueous sodium carbonate. The combined organic extracts were washed with water, brine, dried, and concentrated to provide 4-(4-(3-oxa-8-azabicyclo[3.2.1]octan-8-yl)-6-(3,6-dihydro-2H-pyran-4-yl)-1,3,5-triazin-2-yl)aniline (0.068 g, 74%), which was used in the next step without purification. (M+H) 366.4.
