✦ Synopsis

With sodium borohydride in tetrahydrofuran/ethanol (5 : 1).

the product ( I ) gives a 75 yield of a compound, m.p. 233 "C, that is identical with the recently prepared 2-(diphenylmethyl)imidaz0le[~1. When product ( I ) is boiled for 2 h in tetrahydrofuran/water (2: I ) it affords 2-(hydroxy-dipheny1methyl)imidazole in 72 % yield. Addition of the calculated amount of ethereal hydrogen chloride to a solution of product ( I ) in tetrahydrofuran regenerates the starting material (2) almost quantitatively.
