    Three selectively labeled propynes were prepared either with deuterium or carbon-13 at position 3 and doubly labeled with carbon-13 at positions 1 and 2 by an alkylation reaction from the corresponding labeled or unlabeled monolithio acetylides and dimethylsulfates. Their lithiation with nBuLi gave the corresponding propynyllithium derivatives which reacted with dimethyl squarate to afford the corresponding

    Purpose. The purpose of this study was to evaluate the physical form of 2-tert-butyl-4-methoxy-phenol (BHA) following wet granulation onto common pharmaceutical excipients.Methods. A C-13 label was incorporated into the methoxy group of BHA, the major isomer in synthetic butylated hydroxyanisole. Solutions of the labeled BHA were used to load the labeled BHA onto common pharmaceutical excipients. After air drying under ambient conditions, the mixtures were examined by C-13 MAS and CP/MAS nuclear magnetic resonance (NMR) spectroscopy to evaluate the physical form of the BHA.Results. The data suggested that BHA could exist as either a crystalline or an amorphous component and that amorphous material was either bound to excipients or relatively mobile during the time of the NMR experiment. At 0.1% loading, BHA appeared to be amorphous and mobile in the freshly prepared blends. At 0.5% loading, BHA was shown to be amorphous on microcrystalline cellulose (MCC) and hydroxypropylmethylcellulose (HPMC) while remaining crystalline on lactose, mannitol, calcium phosphate dihydrate, and croscarmellose sodium.Conclusions. Solid-state NMR spectroscopy has been used to probe the physical forms of C-13-labeled BHA granulated onto common pharmaceutical excipients. The techniques described in this paper may be applied to help explain stability changes in formulations containing BHA.
