Procedure
A mixture of 0.56 g (0.166 cmole) of famotidine and 0.222 g (0.166 cmole) of aspartic acid was suspended in dichloromethane (10 ml). The mixture was stirred for 3 hours at room temperature, was filtered, washed with dichloromethane and dried. Weight: 0.782 g. Quantitative yield. Stereoscopically homogenous white microcrystalline solid, similar to milky quartz. Slightly bitter taste. M.P.: 165°-170° C. IR FIG. 2.
