The reaction mixture is stirred for 20 min and triethylamine (5.56 ml) is added. The mixture is partitioned into 4 microwave vials and each portion is heated for 2 h at 1850C in the microwave. The reaction mixtures are recombined and concentrated in vacuo. The residue is treated with 2M methanolic hydrochloride solution (20 ml) and further methanol (5 ml) is added, until complete dissolution occurred. The solution is again concentrated in vacuo and the crude product is purified by flash chromatography (silica gel, eluting with ethyl acetate). The product is crystallized from ether / ethyl acetate 9:1 (v/v) to give 6.8 g (66%) of 2-(1-acetyl-1/-/-indol-3-yl)-3-hydroxycyclopent-2-enone.1H-NMR (200 MHz, CDCI3); delta = 2.31 (s, 3H), 2.55-2.82 (m, 5H), 7.19-7.59 (m, 4H), 8.43 (d, J = 7.5 Hz, 1 H).
