Reaction Steps

To a solution of α,α-Bis(4-pyridinylmethyl)- 2-methoxybenzeneacetonitrile (14.36 g, 43.6 nmol) in ethylene glycol (100 ml), was added KOH (40 ml of a saturated solution) and the mixture was heated at 120°-130° under nitrogen for 20 h. The solution was cooled to room temperature, diluted with 200 ml water, and neutralized with aqueous anmonium chloride to about pH 7. The mixture was extracted with chloroform: isopropanol (4:1) until complete by TLC. The ccrbined extraRs were washed with brine, dried over sodium sulfate, and evaporated (rotary evaporator). The solid was dried in a vacuum oven at 50° and 5 torr to give 7.7 g, 22 mmol, 50% yield of α,α-bis(4-pyridinylmethyl)-2-methoxybenzeneacetic acid as a white powder.
