Procedure

12.1 g of 4-fluoro-benzonitrile, 7.5 g of 2-hydroxypropylamine and 17.4 ml of N-ethyl-diisopropylamine were heated together to 100° C. for 2.5 hours. The mixture was poured onto 250 ml of water, extracted five times with 50 ml of ethyl acetate and the combined organic phases were evaporated down. The product remaining was purified by column chromatography (silica gel; eluant: ethyl acetate) and crystallised by triturating with a 1:1-mixture of tert.butyl-methylether and petroleum ether.
