Versuchsvorschrift

A mixture of the aniline (Intermediate 87, 24.6 g, 107.3 mmol), sodium bicarbonate (13.5 g, 161 mmol) and methyl chloracetate (10.1 ml, 118 mmol) in acetonitrile (30 ml) was heated at 90°-100° for 48 h. Water (200 ml) was added and the mixture extracted with ethyl acetate (3×100 ml). The combined extracts were washed with water (2×100 ml) and brine (100 ml) before drying (Na2SO4) and evaporating in vacuo to leave the crude product as a peach solid. Trituration with ether-hexane (1:1) gave the title compound (Intermediate 88) as a flesh coloured solid (30.3 g; 94%), m.p. 79°-81°.
