The resultant mixture was stirred at room temperature for 15 h, diluted with 10 % K2CO3, and extracted with CH2Cl2 (3 x 20 mL). The combined organic extracts were washed with brine solution, dried over MgSO4, filtered and concentrated in vacuo to afford 107-d2, which was carried on to the next step without purification.; Amine 103 was combined with appropriately deuterated aldehyde 111 in CH2Cl2 (5 mL), Na2SO4 and NaCNBD3 to afford 107.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about exo-3-(3-Isopropyl-5-methyl-4H-1,2,4-triazol-4-yl)-8-azabicyclo[3.2.1]octane, in my other articles.
