Participants

Reaction Steps

To a solution of N-(5-phenylthiothien-2-ylmethyl)-hydroxylamine (2.5 g) in dioxan (50 ml) at room temperature under nitrogen, was added trimethylsilylisocyanate (2.42 g) and the resulting solution stirred for 1 hour, quenched with saturated aqueous ammonium chloride, extracted with ether (2×100 ml), dried over MgSO4 and evaporated under reduced pressure to give a yellow oil. The oil was flash chromatographed on a Sorbsil C60-40/60H column using ether to give a white solid, recrystallised from ether/petroleum ether to give a white crystalline solid m.p. 127°-129° C.
