cysteinyl leukotriene cascade remains highly activated in some asthmatics, even those on high-dose inhaled or oral corticosteroids. Hence, inhibition of the leukotriene C4 synthase (LTC4S) enzyme could provide a new and differentiated core treatment for patients with a highly activated cysteinyl leukotriene cascade. Starting from a screening hit (3), a program to discover oralinhibitors of LTC4S led

An optically active 1-(fluoro-, trifluoromethyl- or trifluoromethoxy-substituted phenyl)alkylamine N-monoalkyl derivative represented by the formula [4] is produced by a process including (a) reacting an optically active secondary amine, represented by the formula [1], with an alkylation agent R2-X, in the presence of a base, thereby converting the secondary amine into an optically active tertiary amine represented by the formula [3]; and (b) subjecting the tertiary amine to a hydrogenolysis, thereby producing the N-monoalkyl derivative,wherein R represents a fluorine atom, trifluoromethyl group or trifluoromethoxy group, n represents an integer of from 1 to 5, each of R1 and R2 independently represents an alkyl group having a carbon atom number of from 1 to 6, Me represents a methyl group, Ar represents a phenyl group or 1- or 2-naphthyl group, * represents a chiral carbon, and X represents a leaving group.
