Abstract
Prepn. of (1S,4S)-2-Y-S-R1- 2,5-diazabicylo (2.2.1)heptane derivs. of formula (I) or their enantiomers, racemates or acid addn. salts comprises (a) reacting a pyrrolidine deriv. of formula (III), or its enantiomer or racemate, with H2NQ(V) to give (I; Y = XR2) and, if necessary, (b) reducing, or hydrolysing, to give (I; Y =H). - (Where Y = H or XR2; R1 = H or 1-6C alkyl; X = SO2 or COO; R2 and R3 = 1-6C alkyl, CF3, benzyl or phenyl (opt. substd. by 1-2 of 1-6C alkyl, halo, NO2, OMe or CF3); R4 = halo or OSO2R3; Q = H or 1-6C alkyl).
