Participants

Reaction Steps

To a solution of 1-(4-pyridinylmethyl)-1H-indol-5-ol (2.4 g) in 50 ml tetrahydrofuran, was added milled K2CO3 (1.5 g), followed by methyl isocyanate (0.65 ml). After stirring at ambient temperature for three hours, the mixture was filtered and the filtrate evaporated to a solid, 3.0 g, m.p. 170° C. This material was eluted on a silica gel column with 2% methanol/dichloromethane via high pressure liquid chromatography (HPLC) and the desired fractions were combined, then evaporated to yield 2.4 g of 1-(4-pyridinylmethyl)-1H-indol-5-yl methylcarbamate, as a solid, m.p. 179°-180° C.
