Claims
- 1. A compound of the formula: ##STR4## the enantiomers and racemates thereof, wherein R.sub.1 is methyl or --CH.sub.2 OR.sub.4, where R.sub.4 is lower alkyl or benzyl; R.sub.2 is lower alkyl and R.sub.3 is phenyl, naphthyl, benzyl; said phenyl or naphthyl each are unsubstituted or substituted with a halogen, lower alkylenedioxy having 2 to 5 carbon atoms, lower alkyl or lower alkoxy, with the lower alkyl and lower alkoxy moieties each having 1 to 7 carbon atoms.
- 2. The compound of claim 1 wherein R.sub.1 and R.sub.2 are methyl and R.sub.3 is phenyl.
- 3. A compound of the formula: ##STR5## the enantiomers and racemates thereof, wherein R.sub.1 is methyl or --CH.sub.2 OR.sub.4, where R.sub.4 is lower alkyl or benzyl; R.sub.2 is lower alkyl and R.sub.3 is phenyl, naphthyl, benzyl; said phenyl or naphthyl each are unsubstituted or substituted with a halogen, lower alkylenedioxy having 2 to 5 carbon atoms, lower alkyl or lower alkoxy, with the lower alkyl and lower alkoxy moieties each having 1 to 7 carbon atoms.
- 4. The compound of claim 3 wherein R.sub.1 and R.sub.2 are methyl and R.sub.3 is phenyl.
